refactor: clean up dialog-model.tsx per code review

- Extract duplicated favorite/recent option builder into toOptions helper
- Simplify showExtra memo to single boolean expression
- Simplify title memo with optional chaining
- Remove dead ref signal and unused DialogSelectRef import
- Inline intermediate variables (q, value aliases)
- Use implicit returns in map callbacks
