Refactor ticket validity handling and improve tests

- Updated tests for Accommodation, Entry, Food, Merchandise, and Sale controllers to use soft deletes for variants and ensure proper inventory counts.
- Enhanced ticket generation logic to resolve validity from soft-deleted catalog sources.
- Introduced a new TicketValidityResolver service to manage ticket validity based on event dates and variant definitions.
- Removed unnecessary database assertions and improved the clarity of validity checks in tests.
- Added comprehensive tests for the new TicketValidityResolver service, ensuring correct handling of event dates and multi-select options.
- Cleaned up unused code and assertions in existing tests for better maintainability.
