chore: restore jiggler.go from dev branch

Replaced custom jiggler implementation with dev branch version:
- Uses rpcAbsMouseReport() instead of gadget.RelMouseReport()
- Maintains same behavior: does NOT call UpdateLastActive()
- Ensures jiggler activity doesn't interfere with session timeouts
- Preserves all multi-session timeout fixes

This change does not affect multi-session functionality.
