- Branding cache moved from localStorage to sessionStorage so it clears
when the mini-app is closed, preventing stale names after admin updates
- Added initialDataUpdatedAt: 0 to all branding queries so fresh data is
always fetched on page refresh while showing cached data instantly
- One-time migration moves existing localStorage value to sessionStorage
- Aurora component now checks WebGL availability upfront, skipping all
hooks and subscriptions when WebGL is not supported
Logo images were exposing the backend API URL in the DOM via <img src>.
Now preloadLogo() fetches the image as a blob and serves it through
URL.createObjectURL(), so only blob: URLs appear in the page source.
Blob is invalidated on logo upload/delete.
