revert(mail): roll back Phase-2 scan-internal — fixes 500 (CJS-extends bundle break)

Phase-2-Rebuild reaktivierte den bekannten imapflow/node-apn util.inherits-Bundle-
Bruch → scan-internal warf 500 → Mail-Filtern (USP) down. Rollback von
scan-internal.post.ts + db/mail.ts auf den funktionierenden Stand (5b57bea).

Schema (folder_scan_state, last_full_sweep_at) + Migration BLEIBEN angewendet —
kein Prisma-Drift; die Spalten warten ungenutzt auf den gefixten Phase-2-Retry.
Root-Cause (warum der inkrementelle imap.status/search-Pfad das Bundle bricht)
muss vor erneutem Phase-2-Deploy in der nitro-Externalize-Config gelöst werden.
