Unify git-issues mail stderr hints via IMAP_SMTP_CONFIG_DOC_REF

**Motivations:**
- Replace per-path messages with canonical doc reference from LeCoffre imap_common.

**Evolutions:**
- mail_common re-exports IMAP_SMTP_CONFIG_DOC_REF; mail-*.py and tickets-fetch-inbox use it for IMAP/SMTP/Gitea token errors.

**Page affectées:**
- git-issues/mail_common.py, mail-list-unread.py, mail-get-thread.py, mail-mark-read.py, mail-send-reply.py, mail-to-issue.py, mail-create-issue-from-email.py, tickets-fetch-inbox.py
