fix: add polling and reset handling for single mode coordinates

Browse source

Enhanced coordinate synchronization in single mode to handle Panel
actions like "Supprimer" (reset to saved values).

Issues Fixed:
- Marker not updating when clicking "Supprimer" button in Panel
- Panel "Supprimer" restores saved coordinates but marker didn't move
- No detection of programmatic field value changes

Solution:
- Add MutationObserver to detect attribute changes on input fields
- Add 500ms polling as fallback for value detection
- Add nextTick() for reactive updates to ensure proper timing
- Handle coordinate reset: when invalid, return to default center
- Proper cleanup with onBeforeUnmount for observers and intervals

Behavior:
- User changes field → marker updates immediately
- User drags marker → fields update immediately
- User clicks "Supprimer" → marker returns to saved position
- Fields cleared → marker disappears, map resets to default center

Technical Details:
- MutationObserver watches 'value' attribute on lat/lon inputs
- Polling checks every 500ms for changes missed by events
- Watcher uses nextTick() to ensure DOM updates complete
- All event listeners and observers properly cleaned up on unmount
