Extends Gridmap and Activated Gridmap to accept a new `sat_orbit` filter and applies it across worked/confirmed grid and VUCC queries, including SAT-specific SQL filtering for LEO, MEO (IO-117), and GEO (QO-100). Updates the gridmap UI to show/hide orbit controls with SAT selection, sends the new filter in AJAX requests, and adds activated-grid summary cards with worked/confirmed counts and satellite class breakdown data from new model methods.
