fix: correct housekeeping module bugs after merge

- Restore migration order: remove spurious v30 birthday-reminders entry
  inserted before CardDAV (v30) and birthday-reminders (v31), which caused
  a duplicate v31 on fresh installs
- Restore birthdayReminderAt() offsetMin handling (regression from merge)
- Fix check-in INSERT: check_out was set to checkIn instead of NULL,
  making sessions invisible to loadOpenSession (IS NULL query)
- Implement check-out path in toggleSession() — only check-in was reachable
- Wrap GET /task-templates in try/catch per project convention
- Fix DELETE response envelopes: { ok: true } → { data: ... }
- Remove housekeeping worker exclusion from GET /auth/users
- Replace toISOString() with local-date helper to avoid UTC date shift
- Use user currency preference in money() instead of hardcoded BRL
- Replace hardcoded #7C3AED fallbacks in style attrs with CSS token
- Add German translations for documents folder and settings housekeeping keys
- Remove DESIGN.md and IMPLEMENTATION.md (AI planning artifacts)

-# Housekeeping Design
-
-## Goal
-
-Housekeeping adds a simplified mobile/PWA module for the cleaner workflow in Oikos. It keeps the existing private-network, authenticated-session security model and exposes no public endpoints.
-
-## User Experience
-
-The `/housekeeping` route is a focused module that follows the same toolbar, tab, card, and chip patterns used by the rest of Oikos:
-
-- **Dashboard**: staff-specific check-in/check-out actions, visits this month, last visit, pending/finished chores, pending payments, and a compact monthly payment chart.
-- **Tasks**: suggested chore templates, custom chore creation, urgency-sorted recurring tasks, and one-tap completion.
-- **Reports**: camera upload plus text description for maintenance occurrences.
-- **Staff**: one or more housekeeper people, contact data, profile pictures, daily rates, and payment schedules.
-
-Accessibility constraints:
-
-- Primary actions are at least 44px high.
-- Check-in/out is a compact top-toolbar action, matching the small action pattern used elsewhere in the app.
-- Status is communicated by text and color, not color alone.
-- Inputs and buttons have explicit labels or accessible names.
-- Icons use the locally bundled Lucide runtime; no external CDN is introduced.
-
-## Data Model
-
-### `housekeeping_work_sessions`
-
-Stores point/finance records:
-
-- `id`
-- `worker_id`
-- `check_in`
-- `check_out`
-- `daily_rate`
-- `extras`
-- `calendar_event_id`
-- `created_by`
-- `created_at`
-- `updated_at`
-
-Monthly amount is calculated as `SUM(daily_rate + extras)` for sessions whose `check_in` belongs to the requested month.
-Each check-in creates a linked local calendar event for the selected staff member. Check-out updates that event end time.
-
-### `housekeeping_decay_tasks`
-
-Stores dynamic recurring cleaning tasks:
-
-- `id`
-- `name`
-- `area`
-- `frequency_days`
-- `last_completed`
-- `created_by`
-- `created_at`
-- `updated_at`
-
-Urgency is computed at read time:
-
-```text
-urgency = (now - last_completed) / frequency_days
-```
-
-Status mapping:
-
-- `overdue`: due date is before today.
-- `today`: due date is today.
-- `ok`: due date is in the future.
-
-Rows with no `last_completed` are treated as overdue.
-
-### `housekeeping_supply_requests`
-
-Stores quick supply requests and links each request to an Oikos shopping item:
-
-- `id`
-- `name`
-- `quantity`
-- `shopping_item_id`
-- `created_by`
-- `created_at`
-
-The supply request transaction always appends an item to the main `shopping_items` table. If no shopping list exists, the backend creates a private authenticated list named `Housekeeping`.
-
-### `housekeeping_maintenance_log`
-
-Stores maintenance occurrences:
-
-- `id`
-- `description`
-- `photo_url`
-- `created_by`
-- `created_at`
-- `updated_at`
-
-`photo_url` accepts self-contained `data:image/png|jpeg|webp;base64,...` values only, keeping uploaded camera photos inside the authenticated Oikos database boundary.
-
-### `housekeeping_workers`
-
-Stores housekeeper-specific employment/payment settings while keeping the person unified with Oikos user/contact/birthday data:
-
-- `id`
-- `user_id`
-- `daily_rate`
-- `payment_schedule`
-- `calendar_color`
-- `notes`
-- `created_at`
-- `updated_at`
-
-The linked `users` row is excluded from normal Family Management and Family APIs through the `housekeeping_workers` association, but remains synchronized with contacts and birthdays.
-Multiple housekeepers can be registered; each has its own linked `users` row.
-`calendar_color` controls the default color used for housekeeping visit events. Visit events use the cleaning icon (`sparkles`).
-
-## REST API
-
-All endpoints are mounted under `/api/v1/housekeeping` and inherit the existing `requireAuth` and CSRF middleware.
-
-- `GET /summary?month=YYYY-MM`
-- `GET /dashboard`
-- `GET /task-templates`
-- `GET /worker`
-- `GET /workers`
-- `POST /worker`
-- `GET /work-sessions?month=YYYY-MM`
-- `POST /work-sessions/check-in`
-- `POST /work-sessions/check-out`
-- `GET /decay-tasks`
-- `POST /decay-tasks`
-- `PATCH /decay-tasks/:taskId`
-- `POST /decay-tasks/:taskId/complete`
-- `DELETE /decay-tasks/:taskId`
-- `POST /supply-requests`
-- `GET /maintenance-log`
-- `POST /maintenance-log`

-# Housekeeping Implementation
-
-## Backend
-
-The module is implemented in `server/routes/housekeeping.js` and registered in `server/index.js` under:
-
-```text
-/api/v1/housekeeping
-```
-
-The registration happens after the global authenticated `/api/v1` middleware, so the module follows the existing Oikos security model:
-
-- Session or API-token authentication required.
-- CSRF required for state-changing session requests.
-- API rate limiting inherited from `/api/`.
-- No unauthenticated housekeeping route.
-
-Database schema is migration `33` in `server/db.js`. The migration creates:
-
-- `housekeeping_work_sessions`
-- `housekeeping_decay_tasks`
-- `housekeeping_supply_requests`
-- `housekeeping_maintenance_log`
-
-Migration `34` adds:
-
-- `housekeeping_workers`
-- `housekeeping_work_sessions.paid_at`
-
-Migration `35` adds per-staff visit tracking:
-
-- `housekeeping_workers.calendar_color`
-- `housekeeping_work_sessions.worker_id`
-- `housekeeping_work_sessions.calendar_event_id`
-
-Each staff profile links to `users.id`. These users are hidden from the normal family list by filtering rows associated with `housekeeping_workers`, while contact and birthday sync remains shared with the existing family-member artifact flow.
-
-The quick supply endpoint uses a SQLite transaction:
-
-1. Resolve the first existing shopping list, or create `Housekeeping`.
-2. Insert a `shopping_items` row.
-3. Insert a `housekeeping_supply_requests` row linked to the shopping item.
-
-If any step fails, the transaction rolls back.
-
-## Frontend
-
-The SPA route `/housekeeping` is registered in `public/router.js` and loads:
-
-- `public/pages/housekeeping.js`
-- `public/styles/housekeeping.css`
-
-The page uses the existing API wrapper in `public/api.js`, so CSRF tokens and auth expiry behavior remain centralized. The UI now follows the standard Oikos module layout: sticky toolbar, horizontal tab chips, and regular cards.
-Check-in/check-out actions live beside each staff member on the Dashboard and are disabled until at least one staff member exists.
-
-Calendar integration creates a local calendar event at check-in, assigns it to the staff user, uses the staff calendar color, and updates the end time on check-out. Calendar event icon selection now opens a dedicated icon picker dialog instead of expanding inline inside the event modal.
-
-The UI intentionally avoids `innerHTML`; rendering uses `replaceChildren()` and `insertAdjacentHTML()` with escaped dynamic values.
-
-## Localization
-
-The module adds:
-
-- `nav.housekeeping`
-- `housekeeping.*`
-
-to every JSON locale under `public/locales`.
-
-Portuguese is the primary text for the cleaner-facing target workflow, with localized strings for the most common existing languages and English fallback text for remaining locales.
-
-## Validation
-
-Backend validation covers:
-
-- Required strings and max lengths.
-- Positive integer `frequency_days`.
-- Non-negative `daily_rate` and `extras`.
-- `YYYY-MM` month filters.
-- Maintenance photos limited to PNG, JPEG, or WebP data URLs under 6 MB.
-
-## Manual Use
-
-1. Navigate to `/housekeeping`.
-2. Use the check-in/check-out button next to the staff member on the Dashboard.
-3. Review the Dashboard metrics and payment chart.
-4. On **Tasks**, choose suggested chores or create a custom recurring chore.
-5. On **Reports**, take/upload a photo and submit a maintenance description.
-6. On **Staff**, create or update one or more housekeepers, contacts, birthdays, rates, and payment schedules.
