feat: add intent extras editing via EditIntentDialog

- Add IntentDef/ExtraDef domain model for intent editing
- Add EditIntentDialogFragment and EditIntentViewModel for editing intent action, data, MIME type, categories, and extras
- Replace ActivityIntent.kt functions with IntentDef-based versions
- Wire EditIntentDialog into ActivityDetailsFragment menu
- Add validation for duplicates, field requirements, and type correctness
- Add intent-related string resources and drawables
- Add unit tests for new ViewModel and utility functions
