Per-track import does heavy synchronous server-side enrichment (metadata,
art, lyrics) that can take 60-90s/track, far longer when external sources
are degraded. The React apiClient (ky) had no timeout, so ky's default 10s
aborted the import-process request client-side even though the server
completed the import (200) and moved the files. The import loop then counted
the aborted call as an error, so the bar stayed at 0 and flipped to 'Failed'
while files imported fine.
Give the two import-process calls (album/process, singles/process) an
explicit 5-min timeout. Scoped to import only -- every other endpoint keeps
the 10s default; bounded, not disabled. Server behavior unchanged.
Adds a test asserting both calls pass the long timeout.
- rely on ky for transport errors across import/staging calls
- keep explicit soft-failure checks for auto-import approval endpoints
- add regression test for approval/rejection soft failures
