Update embedded-postgres dependency to version 2.2.0 in pom.xml.

- Added `LocalDatabaseManager` to support embedded PostgreSQL for local development.
- Introduced `ApplicationMode` enum for configurable runtype (`local` or `server`).
- Updated `MediaManagerApplication` to initialize `LocalDatabaseManager` based on runtype.
- Extended logging configuration for additional modules like `io.zonky.test` and `org.postgresql`.
- Added Maven dependency for `embedded-postgres` and updated configuration examples.
