Database setup for the Website service (#13)

This PR contains the work done to introduce a _Fluent_-based persistence layer for the Website service, selectable at runtime alongside the existing in-memory default, plus the local dev tooling and docs to support it. To provide further details about the work: * Persistence package * The `Driver` and `TLS` enumerations * The `Configuration` type * The `Service` factory that builds the service * `PrepareDB` for migrations registration * The `Probe` for readiness checks. * App integration * Builds the driver, registers migrations, and attaches `Fluent` to the service lifecycle so it starts/stops with the HTTP server. * Migrate-on-boot is gated to the in-memory backend; MySQL/MariaDB is migrated out of band via --database-migrate so shared databases never race on startup. * The `ConfigReader+Properties` extension maps database.* config keys onto the driver. * Library * Added database configuration constants. * The `HealthController` controller gains a readiness probe: `GET /health/ready` checks whether the database is reachable, separate from the existing liveness check. * Others * Updated the `docker-compose` files to support a database service behind a database profile, and hardened for local development * New database targets on the `Makefile` file and overall documentation updated * Updated the `.env.local`, `Dockerfile`, and `README` files to document the persistence workflow, config keys, and local DB commands Reviewed-on: rock-n-code/loud-amsterdam#13 Co-authored-by: Javier Cicchelli <javier@rock-n-code.com> Co-committed-by: Javier Cicchelli <javier@rock-n-code.com>
