Add per-tab time range slicers to Lite query tabs

[erikdarlingdata]

Summary

Interactive time range slicers on all four Lite query sub-tabs:

• Active Queries: Sessions/CPU/Elapsed/Reads per hour
• Top Queries by Duration: Total/Avg CPU, Duration, Reads, Writes
• Top Procedures by Duration: Same metrics as Query Stats
• Query Store by Duration: Total/Avg CPU, Duration, Reads, Executions

Each slicer:

• Respects the global time picker (1h/4h/24h/7d) and reloads on change
• Updates metric + chart when the grid sort column changes (total vs avg)
• Snaps to hourly bucket boundaries for accurate filtering
• Supports Local/UTC/Server time display mode
• Drag handles to narrow time range, Ctrl+scroll to zoom

Also includes date column fixes from #649/#651:

• Query Stats: Last Execution + Creation Time columns added after Database
• Procedure Stats: Last Execution added, Cached Time moved from end to after Type
• Query Store: Last Execution + First Execution moved to after Plan ID

Test plan

• Build: 0 errors
• All four slicers render and load data
• Slider drag filters grid results
• Sort column changes slicer metric label and chart
• Time picker change reloads slicer
• Local/UTC/Server display mode updates slicer labels
• Hour-boundary snapping prevents data disappearing at bucket edges
