The `date` import from validate.js shadowed the `date` field from req.body, so SQLite received a function reference instead of a string when updating a budget entry - causing a TypeError. Fix by aliasing the import to `validateDate` and adding `date` to the req.body destructuring. Closes #8 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
