Add min completion percentage filter to Album Completeness job

New setting: Min Completion % (default 0 = disabled). Skips albums
where the user has fewer than N% of tracks — filters out playlist
imports where a single track exists but the full album was never
intended to be downloaded. Catches real failed downloads (6/12)
while ignoring incidental singles (1/12).
