Initial extraction: groombook/api from groombook/app monorepo

Part of GRO-802 monorepo breakdown. Changes: - Extract apps/api/ as the main API service - Inline packages/db/ (database schema, migrations, utilities) - Inline packages/types/ (shared TypeScript types) - Add CI workflow for lint, typecheck, test, build, docker - Port Dockerfile with 4 stages: runner, migrate, seed, reset Co-Authored-By: Paperclip <noreply@paperclip.ing>
