When an instance sits behind a reverse proxy that requires HTTP Basic Auth,
every detection probe (/info, /api/v1/config, /api/v1/stats, /healthcheck,
/config) returns 401 before reaching the real backend, so the type cannot be
identified. Re-throw APIError.unauthorized from each probe instead of
swallowing it, and have detectWithResult convert the first 401 it sees into
DetectionError.basicAuthRequired. Add a basicAuthHeader parameter so the
caller can retry detection after the user provides credentials; if a retry
also returns 401, surface basicAuthInvalid instead.
Remove 32 non-dotted keys (16 unused format specifiers, 16 word keys)
and replace with properly namespaced dotted keys following the existing
convention (common.*, player.*, search.*).
Display the view options button, channel menu, and content type tabs
immediately when the cached header is shown, instead of waiting for
the full channel data to load. The spinner now appears only in the
content area below the tabs.
Adds a "Proxy videos" toggle in instance settings that routes video
streams through the instance instead of connecting directly to YouTube
CDN. Includes auto-detection of 403 blocks and live re-application of
proxy settings without requiring app restart or video reload.
Shows an orange "DEV" capsule next to the iCloud row in Settings and a
development environment notice at the top of iCloud settings, helping
distinguish CloudKit dev environment from production during development.
