fix: refactor playback controls and consolidate XML tag constants

- Remove commented-out playback logic from share page
- Simplify tool call handling in PlaybackControls by removing toolPlaybackIndex state
- Fix tool navigation initialization and synchronization issues
- Consolidate HIDE_STREAMING_XML_TAGS constant from multiple files into utils.ts
- Add 'create-tasks' to hidden streaming XML tags list
- Improve tool call side panel index synchronization
- Add cursor pointer styling to slider components for better UX
- Remove unused toolName tracking in chunk processing
- Fix tool index initialization to start at 0 instead of -1
