Fix automation badge overflow, dashboard crosslinks, compact numbers, icon grids, OpenRGB brightness

UI fixes:
- Automation card badge moved to flex layout — title truncates, badge stays visible
- Automation condition pills max-width increased to 280px
- Dashboard crosslinks fixed: pass correct sub-tab key (led-targets not led)
- navigateToCard only skips data load when tab already has cards in DOM
- Badge gets white-space:nowrap + flex-shrink:0 to prevent wrapping

New features:
- formatCompact() for large frame/error counters (1.2M, 45.2K) with hover title
- Log filter and log level selects replaced with IconSelect grids
- OpenRGB devices now support software brightness control

OpenRGB improvements:
- Added brightness_control capability (uses software brightness fallback)
- Change-threshold dedup compares raw pixels before brightness scaling
