chore: clean up biome lint warnings — all non- intentional resolved

- Remove 25 unused imports across 14 test files
- Remove 1 unused variable (rename with _ prefix)
- Fix 2 noBannedTypes (Function → (...args: unknown[]) => unknown)
- Fix 1 useTemplate lint (string concat → template literal in merge-config.cjs)
- Fix 1 useNodejsImportProtocol (merge-config.cjs)
- Fix 2 noTemplateCurlyInString (generate-drizzle-schema.mjs generator code)
- Auto-fix formatting + import sorting across modified files
- 221 remaining warnings: intentional noExplicitAny in prisma-facade.ts (Prisma compat layer)
- 0 tsc errors, 583 tests passing
