Add Veeam Cloud Connect importer (inbox-style staging flow)
- cloud_connect_importer.py: parse Cloud Connect daily report HTML,
upsert tenant rows into cloud_connect_accounts, create JobRuns for
linked accounts (deduped via external_id)
- routes_cloud_connect.py + cloud_connect_accounts.html: inbox-style
review page with create/link/unlink actions (mirrors Cove flow)
- CloudConnectAccount model: staging table unique on user × section
- migrate_cloud_connect_accounts_table(): creates table + indexes,
registered in run_all_migrations()
- mail_importer.py: detect btype=="cloud connect report", call
upsert_cloud_connect_report(), auto-approve on success
- base.html: sidebar link "Cloud Connect" for admin/operator
