fix: resolve all biome lint errors and type issues

- Add file-level biome-ignore for noExplicitAny in prisma-facade.ts
  (intentional any for Prisma API compatibility surface)
- Fix noNonNullAssertion errors in cached-db.ts (redis null-guard fixes)
- Auto-fix formatting + organizeImports across modified files
- 0 tsc errors, 0 biome errors, 583 tests passing
