feat(masterdata): add ÖTO seed data, regulation validation tests, and profile module integration

- Introduced ÖTO 2026-compliant seed data (`V008__Seed_OETO_2026_Data.sql`) for tournament classes, license matrix, and age groups.
- Added `RegulationSeedVerificationTest` to validate repository queries and domain eligibility logic.
- Implemented a new `profile-feature` module covering user profile management and ZNS linking.
- Integrated the `profile-feature` into the desktop shell and frontend with Koin DI configuration.
- Extended CHANGELOG, ROADMAP, and architecture documentation to reflect related changes.
