Resolves FOREIGN KEY constraint failed (500) on DELETE /api/admin/users/:id
and DELETE /api/auth/me when the target user had rows in trip_members.invited_by,
share_tokens.created_by, budget_items.paid_by_user_id, journeys.user_id,
journey_entries.author_id, journey_contributors.user_id, or
journey_share_tokens.created_by — none of which had ON DELETE clauses.
Introduces deleteUserCompletely() in userCleanupService.ts which wraps all
cleanup and the final DELETE FROM users in a single transaction. Both
adminService.deleteUser and authService.deleteAccount now call it instead of
the bare DELETE. Tests ADMIN-005b and AUTH-040 cover all reference types
including notification sender/recipient and notice dismissals.

* Fix multer silent rejections and error handler info leak
- Revert cb(null, false) to cb(new Error(...)) in auth.ts, collab.ts,
and files.ts so invalid uploads return an error instead of silently
dropping the file
- Error handler in app.ts now always returns 500 / "Internal server
error" instead of forwarding err.message to the client
* Use statusCode consistently for multer errors and error handler
- Error handler in app.ts reads err.statusCode to forward the correct
HTTP status while keeping the response body generic
