Guillaume BOURGEOIS 84be770928 feat(gmail-single-user): new single-mailbox Gmail integration
Gmail for one mailbox over OAuth 2.0 (no service account / delegation):
auth-link + exchange-code to obtain a refresh token, connectivity test,
message search/get, send/reply with attachments, attachment retrieval,
and get_incidents ingestion with an OCSF mapper. Refresh-token grant,
stdlib-only (no extra Python dependencies).
