Restore from Gitea ZIP snapshot (12.08.2026) after full instance reinstall

Git history was lost when the previous Gitea instance was wiped and reinstalled due to an unresolved corruption bug — this commit is the last known-good file content, exported before the reinstall. Prior commit history is not recoverable through this path.

+/**
+ * Rotates the AES-256-GCM master key used to encrypt stored mailbox
+ * credentials. Decrypts every stored IMAP/SMTP/CalDAV password under the
+ * old key and re-encrypts under a newly generated one, in a single
+ * transaction, then prints the new key so it can be written into
+ * /etc/ai-chief-of-staff/secrets.env.
+ *
+ * Usage: OLD_KEY=<base64> npx tsx scripts/rotate-credential-key.ts
+ * (reads the current key from CREDENTIALS_ENCRYPTION_KEY if OLD_KEY is unset)
