test: 81 unit tests for tickets (data, storage, transcript, ui)

- tests/test_data.py: models serialization, enums, roundtrip
- tests/test_storage.py: CRUD JSON, cache, persistence
- tests/test_transcript.py: HTML generation, escaping, attachments
- tests/test_ui.py: button callbacks with mocked interactions
- Fixed: transcript.py attachments access (dataclass not dict)
