Fix stale test assertions and mock real Bluesky API calls in tests
Update loading page assertions to match the custom div-based progressbar
(role="progressbar" + aria-valuemax) instead of the removed <progress>
element. Fix backfilled-user test to expect the render-path getProfile
call. Add AtprotoClient swaps to all ClickHouse-backed profile tests
that were hitting the live Bluesky AppView API.
