feat: integrate new desktop shell and extend backend & ADRs

- Added `meldestelle-desktop` module using JVM/Compose Desktop, registered in `settings.gradle.kts`.
- Integrated new screens and desktop navigation into core: `Veranstaltungen`, `TurnierDetail`, etc.
- Expanded backend with `ExposedFunktionaerRepository` in `officials-infrastructure`.
- Completed ADRs for bounded context mapping (`ADR-0014`) and context map (`ADR-0015`).
- Updated and extended project documentation with session logs and architecture decisions.
