fix(federation): store absolute URLs for replicated user avatars

Browse Source 
Bare filenames stored on replicated user stubs can't be resolved by
the home WS (normalizeUserAssets only runs for remote origins).
Now resolves avatar/banner to absolute URLs pointing to the user's
home instance so they render correctly without page refresh.
Also overwrites stale bare filenames from the prior deploy.
