feat(discover): full reset — clear + rebuild suggestions

Browse Source 
POST /api/discover/reset sets discover.resetRequested; the worker, at the
start of the next sweep, clears all PENDING suggestions + contributions +
seed throttles and nulls WatchedArtist.lastDiscoveredAt (keeping
followed/wanted/dismissed decisions), then regenerates everything with current
logic. A 'Reset' button on /discover (2-step confirm) triggers it.

worker 247, web 190 tests.
