feat: add disabled state UI for Recent Events widget

Show helpful message when Recent Events tracking is disabled in tracker config.

Changes:
- Check if recentEvents is enabled in trackerConfig before rendering
- If disabled, show dimmed widget with overlay message:
  - Info icon + explanation text
  - "Enable in Tracker Settings" button
  - Button opens Tracker Settings and switches to Info Box tab

UX Improvements:
- Widget opacity reduced to 0.6 to indicate disabled state
- Message centered with clear visual hierarchy
- Button has hover/active states with elevation feedback
- Clicking button directly navigates to the right settings location

Technical Implementation:
- attachDisabledStateHandlers() opens Tracker Settings modal
- Auto-switches to Info Box tab after 100ms delay
- Graceful fallback if button not found (console warning)

CSS Additions:
- .rpg-widget-disabled: Dimmed overlay state
- .rpg-widget-disabled-message: Centered message container
- .rpg-widget-enable-btn: Styled action button with hover effects

Benefits:
- Users immediately understand why Recent Events isn't updating
- One-click access to fix the issue
- Clear visual feedback about widget state
- Pattern can be reused for other widgets (Skills, etc.)

Next Steps:
- Apply this pattern to other widgets that depend on tracker config
- Consider adding similar disabled states for Skills, Stats, etc.
