feat: external Learning Hub toggle + applicant help button

- Add admin settings: learning_hub_external, learning_hub_external_url, support_email
- Jury/Mentor nav respects external Learning Hub URL (opens in new tab)
- RoleNav supports external nav items with ExternalLink icon
- Applicant header shows Help button with configurable support email
- Settings update mutation now upserts (creates on first use)
- Shared inferSettingCategory for consistent category assignment
