fix(db): use TEXT for user_id columns across entire codebase

Better Auth generates non-UUID user IDs (32-char base62 format like
'otUe1YrfENPdHnrF3g1vSBfpkQfambCZ'). Changed all `uuid('user_id')` to
`text('user_id')` in Drizzle schemas for consistency with auth system.

Affected packages/apps:
- apps/calendar, clock, picture, zitare
- games/figgos, voxelava
- packages/manadeck-database, news-database, uload-database
- services/mana-core-auth (feedback schema)
