Subject: [PATCH] Remove ACARS section from left sidebar menu

ACARS controls are now in the collapsible sidebar next to the map,
so the redundant section in the left settings panel is no longer needed.

- Remove ACARS Messaging section from aircraft mode settings
- Remove unused JS functions (toggleAcarsPanel, setAcarsRegion, etc.)
- Keep addAcarsToOutput helper used by main sidebar
