backend: drop unreliable artist *= filter entirely — yt-dlp artist field
is empty for many label-distributed YTM tracks (NoAki, etc.), causing
correct results to be rejected in Steps 1-2 and falling through to Step 3
anyway. Search query already targets the right artist; title keyword +
duration are sufficient. Simplifies cascade from 8→8 steps but with fewer
wasted filter attempts.
frontend: add 3s delay before polling getScanStatus (gives Navidrome time
to actually start the scan), and 5s buffer after scan completes (lets DB
writes settle). Fallback to 30s fixed wait if scan API is unavailable.
