fix(imports): run silence guard at the integrity/length check, before quality

The silence guard sat after the quality guard, so a strict quality profile
quarantined every file before silence detection ever ran. Move it to right
after check_audio_integrity (where the length is verified) and before the
AcoustID/quality gates, so a mostly-silent file is caught regardless of its
quality verdict and reported with the correct reason. Same quarantine +
next-candidate retry pattern (trigger='silence').
