fix: add showProjectIcons and weekStartDay to Prisma schema + route

Both fields existed in the DB but were missing from schema.prisma,
so the Prisma client didn't know about them. The client has been
regenerated (prisma db push). Added both fields to:
- prisma/schema.prisma (with correct defaults)
- GET select, PATCH destructure, updateData, PATCH select in route.ts

This resolves the 500 errors on PATCH /api/user/profile that occurred
when saveSetting() tried to persist these fields.
