- Updated TicketGeneratorService to resolve and assign validity times to tickets.
- Refactored ticket generation logic to remove legacy date fields and use validity time.
- Introduced timezone support for tenants to handle service dates correctly.
- Updated migrations to remove deprecated columns and add foreign keys for validity times.
- Modified seeders and tests to accommodate new validity time structure.
- Enhanced tests to validate ticket generation and validity time behavior.
