merge: integrate upstream RPG attributes customization system

Merged commits from upstream/main (d870731):
- Add customizable RPG attributes (STR/DEX/etc) with add/remove/rename
- Fix character stats editing (0% display bug, missing Stats line creation)
- Add mobile font-size overrides for better readability
- Fix together mode rendering order (render panels before cleaning DOM)
- Fix temperature unit toggle (C/F) and thermometer thresholds
- Add buildAttributesString() for custom attribute names in AI prompts

Upstream Features:
- trackerConfig.rpgAttributes array replaces showRPGAttributes boolean
- Per-attribute enable/disable, custom names, reordering
- Tracker editor UI for managing attributes
- Custom attribute names appear in AI prompts and dice rolls
- Backward compatible migration from old boolean toggle

Merge Conflict Resolution:
- src/systems/integration/sillytavern.js:
  * Kept both: upstream's "render before DOM cleaning" + our refreshDashboard()
  * Result: render panels → refresh dashboard → update DOM
- style.css:
  * Kept both: our Widget Integration CSS + upstream's Mobile Font Overrides
  * Our Recent Events width fix (width: 100%) preserved
