L7: Canceled status chip now uses 'subtle' color (neutral) instead of 'warning'
(amber) -- distinguishing it from paused which remains amber.
M13: Proxy URL and YouTube PO-token inputs now use type="password" to mask
credentials, matching updateToken. Proxy URLs can carry user:pass; PO tokens
are opaque secrets.
M37: Rewrite two dev-facing hints -- youtubePlayerClient now says 'how AeroFetch
identifies itself to YouTube' instead of citing yt-dlp internals; filename
template says 'Controls how saved files are named' instead of 'yt-dlp output
template'. Remaining hints (cookie browser, aria2c, etc.) were already clean.
typecheck + 242 tests + eslint + prettier green.
