docs(pro): add the on-prem support bundle page and its email setup

[stevewallone]

Description

Documents a new DefectDojo Pro feature for on-prem Docker Compose installs: a superuser can collect a support bundle (container logs and redacted settings) from Settings > License & Support > Support Bundle, download it, and email it to DefectDojo support, instead of running commands on the server and attaching log files by hand.

What changed

• New page docs/content/get_started/pro/onprem/docker_compose/support_bundle.md:
  • what a bundle contains and the steps to collect one, including choosing the log period (last hour, 24 hours, 7 days, or all available);
  • how much log a bundle holds (50 MB per container and 250 MB in all, newest lines first), the MANIFEST.txt that names trimmed logs, and the free disk space check;
  • setting up email: Email Settings first, DD_EMAIL_URL as the fallback, the sender address under System Settings, and the page's Test Connection button;
  • notes for Google Workspace and Gmail (app passwords, or allowing the server on the SMTP relay) and for Microsoft 365, plus Download as the fallback;
  • container log retention, which dojo-compose-cli now bounds;
  • troubleshooting for the host collector, disk space and email.
    The page says it applies to Docker Compose only and not to Helm installs, where the feature is hidden.
• support_diagnostics.md links to the new page.
• messaging_connectors.md pointed SMTP setup at System Settings. It now points at Settings > System > Email Settings, with the sender address under System Settings.

Text-only change; no code or screenshots.

Pairs with the DefectDojo Pro change and a dojo-compose-cli release that implement the feature; please merge them together.

Review (separate session): request changes

I checked this against the current heads of the paired Pro and dojo-compose-cli changes. Since this was written, those changes added recovery behaviour that the page doesn't describe yet.

Out of date

1. How it works says dojo-compose-cli installs two systemd units. There are now three: dojo-support-bundle.timer also starts the service 5 minutes after boot and every 30 minutes, to mark bundles whose collection stopped as failed.
2. Troubleshooting: "A bundle stays Queued"
   • A request the host doesn't pick up within 10 minutes is now shown as Failed ("The host collector did not pick up this request").
   • A collection still running after 2 hours is shown as Failed, with a Host Collector Stopped warning on the page.
   • In both cases, Collect Logs is available again once the collector is fixed. Worth saying that, and keeping the systemctl status / journalctl commands.
3. Container log retention should say that:
   • an operator's own COMPOSE_FILE (from the environment or the install's .env) is honoured, with the logging file appended to it;
   • services that already set their own logging: are left unchanged.

Should fix

• No milestone. Please attach the next open milestone, for the same release as the paired Pro change.

Nit

• The menu item is named Email Settings; the page says "Settings > System > Email" in three places.

Checked and accurate: what a bundle contains; the per-container and total log caps; the 200-line fallback; the free-space check, which lowers the per-container cap and fails with the MB free; the 15 MB email limit; the --since values of diagnostics collect; the Gmail and Microsoft 365 guidance; and the gating (Docker Compose only, not Cloud or Helm).
