[fix](trx-frontend-http): show all rigs data on map panel regardless of active rig

Remove rig_id filtering from dispatchDecodeMessage and dispatchDecodeBatch
so that decode data from all rigs (including remote/non-primary) flows into
the map. Also remove the rig_filter query param from decode history fetch
so all history is loaded. The existing map rig filter dropdown handles
visibility filtering via marker.__trxRigIds.
