feat: Add comprehensive edit screen to new listing wizard

- Replace individual state structs with unified ListingDraft struct
- Add EditingListing state with field selection interface
- Implement individual field editing states (Title, Description, Price, Slots, StartTime, Duration)
- Add field-specific keyboards with Back buttons and Clear functionality for description
- Update all handlers to use ListingDraft instead of separate state structs
- Rename Confirming to ViewingDraft for clarity
- Add proper validation and error handling for all field edits
- Enable seamless navigation between edit screen and confirmation
- Maintain all existing functionality while adding edit capabilities
