varaverk: monitor tab overhaul — grid layout, dynamic thresholds, new cards

Layout:
- Switch from three flex rows to single CSS grid (repeat(8,1fr)) — eliminates
  gap-count discrepancy between rows; span 1/2/4/8 cards are now pixel-identical
  across all rows regardless of how many cards share the row

New cards:
- Scripts card: last-run status (ok/warn/running/unknown), clickable filter pills,
  7-row scroll, flex:1 matching Power/Parity
- Streams card: live per-second progress counters, color-coded play buttons
  (blue=live, orange=transcoding, green=direct, yellow=paused), server badges
  with counts, left-fill column layout (3 per col)
- Transcode card: NVMe indicator, active session count + scrollable list,
  session rows with server icon + title + type + method

Dynamic thresholds:
- vv_disk_thresholds() reads /boot/config/plugins/dynamix/dynamix.cfg
- Disk utilization bars: green/orange/red based on warning/critical settings
- Temperature colors: hot/max for HDD, hotssd/maxssd for SSD/NVMe
- Thresholds update every poll cycle; changing Unraid settings takes effect automatically

Other:
- SSD path detection uses findmnt FSTYPE to exclude tmpfs/ramfs (fixes RAM
  being reported as SSD transcode target)
- varaverk.css h3: add white-space:normal + overflow:hidden to neutralise
  any Unraid global h3 styles that could force card width
