fix: add accessibility attributes, display full verse reference, reset tabs on verse change, add character limit

- Add aria-label to close button for screen reader support
- Add dynamic aria-label to bookmark button (Add/Remove bookmark)
- Add aria-label and character counter to notes TextField
- Wrap mobile bottom sheet in proper dialog semantics (role="dialog", aria-modal="true")
- Display full verse reference (Book Chapter:Verse) instead of just verse number
- Add useEffect to reset tab to Notes when verse changes for better UX
- Add 500 character limit to notes with visual counter
