EmberLedger

EmberLedger v1.2.2

Performance hotfix focused on reducing unnecessary background refresh work.

Changes:
- Reduced unnecessary once-per-second refresh work while the main tracking window is hidden.
- Reduced unnecessary once-per-second refresh work while the standalone Session window is hidden.
- Limited ticker-driven action bar refreshes to cases where the main panel action bar is visible.
- Added a fresh Session window refresh when the Session window is shown, so hidden-window throttling does not leave stale text.
- Preserved launcher updates.
- Preserved manual refresh and event-driven updates.

No changes made to:
- Tracking logic
- Sorting
- Session calculations
- Saved-variable migration structure
- Launcher behavior
- Blizzard frame behavior
- Seed flyout
- Minimap button
- Import/export tools
- Backup tools

Validation:
- Zip integrity check passed.
- Code scan found no risky Blizzard frame-closing calls.
- Code scan found no TODO/FIXME markers.

Notes:
This update is intended to reduce possible FPS drops or stutters
