Update Kotlin models and iOS Swift to align with new Go API format

- Update all Kotlin API models to match Go API response structures
- Fix Swift type aliases (TaskDetail→TaskResponse, Residence→ResidenceResponse, etc.)
- Update TaskCompletionCreateRequest to simplified Go API format (taskId, notes, actualCost, photoUrl)
- Fix optional handling for frequency, priority, category, status in task models
- Replace isPrimaryOwner with ownerId comparison against current user
- Update ResidenceUsersResponse to use owner.id instead of ownerId
- Fix non-optional String fields to use isEmpty checks instead of optional binding
- Add type aliases for backwards compatibility in Kotlin models
