Subject: [PATCH] Lite: add column-level filtering to all data grids (#18)

Port the Dashboard's column filter system to Lite. Users can now click
a filter icon on any column header to open a popup with operator
selection (contains, equals, greater than, etc.) and filter value input.
Filters persist across auto-refresh cycles. Active filters show a gold
icon; inactive filters show dim.

New generic DataGridFilterManager<T> eliminates per-grid boilerplate
by encapsulating filter state, unfiltered data capture, LINQ filtering,
and button style updates for each of the 11 DataGrids.

Tested: filters apply/clear correctly, icons toggle color, data refreshes
preserve active filters.
