Add filters to remaining Dashboard FinOps grids

[erikdarlingdata]

Summary

• Add column filter buttons to IdleDatabasesDataGrid (4 columns: DatabaseName, TotalSizeMb, FileCount, LastExecutionTime)
• Add column filter buttons to TempdbPressureDataGrid (4 columns: Metric, CurrentMb, Peak24hMb, Warning)
• Add column filter buttons to IndexAnalysisSummaryGrid (28 columns)
• Add column filter buttons to IndexAnalysisDetailGrid (15 columns)

All use the existing FinOpsFilter_Click handler and ColumnFilterButtonStyle. Existing ElementStyle properties (right-alignment, tooltips) preserved on all columns.

Test plan

• Open FinOps > Optimization tab, verify IdleDatabases and TempDB grids show filter buttons
• Open FinOps > Index Analysis tab, verify both Summary and Detail grids show filter buttons
• Click filter buttons, confirm filter popup works and filters data correctly
• Verify right-aligned numeric columns still align correctly

Replaces plain text headers with composite headers (filter Button + bold TextBlock) across columns in multiple DataGrids (Recommendations, Utilization, Database Resources, Storage Growth, Database Sizes, Index Analysis, Optimization, High Impact, Application Connections, Server Inventory, etc.). Each filter button is wired to FinOpsFilter_Click handler with a Tag binding to the column's data property.
