video Tools: rehydrate scan state on page refresh (parity with music)

Browse source 
The scan runs server-side, so on load video-scan.js now polls
/api/video/scan/status and, if a scan is in progress, restores the live UI
(Cancel button, moving progress bar, phase) and resumes polling — instead of
showing Idle after a refresh. Also re-checks when the Tools page is shown.
Because it re-emits the progress event, the Library/Dashboard scan affordances
rehydrate too.
