feat(jira): per-user auth, lifecycle hooks, admin config endpoints

- Add jira_api_token field to User model + migration b042
- Per-user Jira client: user's corporate email + personal Atlassian token
- Admin-configurable Jira URL/project via system_configs (GET/PATCH /system/jira-config + POST /system/jira-test)
- Auto-create Jira ticket when a test is created (non-fatal)
- Push lifecycle comments on every state transition: draft→red_executing→blue_evaluating→in_review→validated/rejected→draft
- Rich ticket descriptions with technique, MITRE ID, priority from severity, labels
- UserOut.jira_token_set (bool) instead of exposing raw token
- PATCH /users/me/preferences now accepts jira_api_token
