fix(dashboard): move Exit Edit Widget Mode button to priority topbar

Physically moved 'Exit Edit Widget Mode' button from menu-only section
to priority buttons section in the topbar (header-right).

Changes:
- Moved button from line 52 (menu-only section) to line 27 (priority section)
- Button now appears right after 'Tracker Settings' in the topbar
- Changed from 'rpg-overflow-btn rpg-menu-only-btn' to 'rpg-priority-btn'

Button order in topbar:
1. Lock/Unlock Widgets
2. Enter Edit Mode
3. Tracker Settings
4. Exit Edit Mode ← Now here in the actual topbar!

The button is now always visible in the main header next to tabs and
hamburger menu, not hidden in dropdown menus.
