chore(10-01): generate + apply v1.1 DB migration (0001_famous_mad_thinker)

- Generated via drizzle-kit generate from updated schema.ts
- SQL is additive-only: CREATE TABLE app_config + ALTER TABLE ADD COLUMN (3x) + ADD CONSTRAINT UNIQUE
- Applied to live dev MariaDB via direct SQL execution (drizzle-kit migrate journal hash mismatch
  with legacy migration tracking; DDL applied + hash recorded in __drizzle_migrations manually)
- Verified: MIGRATION OK via live DB SHOW COLUMNS / SHOW TABLES query
- No DROP/TRUNCATE statements in generated SQL (grep returns 0)
