Fix: StripOverlayLayer initialization timing issue

Moved StripOverlayLayer and ConfirmationBar initialization to occur AFTER
ScryingPoolStrip is created (via roleRenderer.openStrip()). This fixes the
console warning: 'StripOverlayLayer: ScryingPoolStrip not found, appending to body'

The issue was that StripOverlayLayer.init() was trying to find
.scrying-pool__roster-strip before it was created. ScryingPoolStrip is
created lazily when roleRenderer.openStrip() is called.

Additionally, made both components GM-only since:
- ConfirmationBar is in src/ui/gm/ and is only useful for GMs
- StripOverlayLayer is currently only used by ConfirmationBar
- ScryingPoolStrip is only created for GMs

This ensures proper positioning of ConfirmationBar relative to ScryingPoolStrip.
