feat: consistent IconGridSelect sizing + descriptions + filter upgrades

- Added desc text to all 40+ grid items (EN + RU)
- compact prop on all IconGridSelect in compact form sections
- Fixed compact width to fill grid cells (removed width:auto)
- Replaced <select> filter dropdowns with IconGridSelect on config pages
- Replaced <select> provider filters with EntitySelect on tracker pages
- Dashboard filters constrained to fixed widths (not full row)
- Added filtering to command-template-configs and providers pages
- providerTypeFilterItems() with "All" option for filter contexts
