feat(analytics): expand umami tracking in todo, calendar, and contacts apps

Todo:
- Track projectCreated, projectDeleted, labelCreated
- Track taskUncompleted
- Track quickAddUsed via QuickInputBar

Calendar:
- Track eventUpdated, eventDeleted
- Track calendarCreated, calendarDeleted

Contacts:
- Track contactUpdated, contactDeleted, contactFavorited, contactArchived
- Track searchPerformed in SearchModal
- Track contactExported in ExportModal
- Track contactImported for both Google and file (vCard/CSV) imports

Also extends analytics event helpers with new event types.
