refactor: remove redundant Edit Trackers button from hamburger menu

Remove duplicate "Edit Trackers" button from hamburger menu since there's
already a Tracker Settings button in the dashboard header.

Changes:
- Removed "Edit Trackers" button from template.html hamburger menu
- Updated Settings button to full width (removed .rpg-btn-half class)
- Changed dashboard button ID from 'rpg-dashboard-tracker-settings' to
  'rpg-open-tracker-editor' to become the canonical button
- Removed redundant event handler in dashboardIntegration.js that was
  clicking the old hamburger button

Benefits:
- Reduces UI clutter in hamburger menu
- Single source of truth for Tracker Settings button (dashboard header)
- Existing code in trackerEditor.js, infoBoxWidgets.js continues to work
  via jQuery event delegation on ID 'rpg-open-tracker-editor'

Technical Notes:
- jQuery delegation $(document).on('click', '#rpg-open-tracker-editor', ...)
  works for any element with that ID, not just a specific one
- No changes needed to trackerEditor.js or widget disabled state handlers
- Dashboard button is now the canonical "Edit Trackers" trigger
