Fix: StripOverlayLayer initialization timing - proper architecture

Resolved the 'ScryingPoolStrip not found, appending to body' warning by
restructuring the initialization flow:

1. ScryingPoolStrip now creates its own StripOverlayLayer lazily via getter
2. ScryingPoolStrip.stripOverlayLayer returns the layer instance
3. ConfirmationBar accepts ScryingPoolStrip/RoleRenderer and extracts stripOverlayLayer
4. RoleRenderer exposes public .strip getter for ScryingPoolStrip access
5. All components only initialized for GM users (where ScryingPoolStrip exists)

This ensures:
- StripOverlayLayer is created AFTER ScryingPoolStrip DOM element exists
- ConfirmationBar renders correctly positioned within the strip
- No fallback to document.body needed
- Proper separation of concerns (strip owns its overlay layer)
