feat(ml): stricter auto-apply defaults to cut misfires (milestone 139)

head_auto_apply_precision 0.97→0.98, head_auto_apply_min_positives 30→50, ccip_auto_apply_threshold 0.92→0.95 (operator-asked). Model defaults change for fresh installs; migration 0081 bumps the existing singleton row IFF still at the old default (won't clobber a deliberate operator change). ml_admin bounds already permit these. Fixed a stale comment in the auto-apply test. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CDgx8bQS5YrGRK76v8HUnM
