feat(doctor): improve duplicate filename conflict UX with confirm modal, syntax-format nav, and i18n

- Remove [LoRAs] prefix noise from conflict detail display
- Limit inline conflict groups to 5, show remainder count
- Add 'Switch to Full Path Syntax' action in conflict card
- Add confirmation modal before resolving conflicts (shows rename strategy)
- Register resolveFilenameConflictsModal in ModalManager (fix no-op showModal)
- Switch to Interface section and add highlight animation on syntax-format nav
- Sync and translate conflictConfirm strings across all 10 locales
