feat: Controller hotbars with cross layout, separate storage, and sync with game

- Add controller hotbars: 8 cross bars (L2/R2 style), separate from normal hotbars 1-8
- Controller bar slot data stored in config (not game StandardHotbars) so layouts can differ per mode
- Drag-and-drop on controller bars: from game, shift+drag rearrange, release outside to clear
- Independent controller bar keybinds with modifier+trigger combinations (e.g. L2+South)
- Optional 'Sync bar mode with game client': follow Character Config Mouse/Gamepad toggle (PadMode)
- Clone/copy actions: normal hotbars ↔ controller bars
- Restore controller bar layout button; deploy to devPlugins on Release build
