Biomekka 1.8.24

Dashboard-only storm dice polish.

Changed:
- Restyled the storm dice so it has visible polyhedral-style edge/facet lines.
- Slightly darkened and toughened the dice appearance so it looks less like a mint jelly blob.
- Kept the existing dice roll animation.
- Added a small random final dice angle/offset on each new storm roll.
- The final angle is limited to roughly -7 to +7 degrees so the number stays upright, just slightly wonky.

Not changed:
- No sensor, pin, relay, Goblin command, MQTT topic, telemetry schema, solar logic, storm logic, camera/feed, or HA changes.
