The page every migration pass is started from.

Context:
  - inventory_job:  The most recent inventory Job, or None
  - staging_job:    The most recent staging Job, or None
  - staging_queued: Whether a staging pass is already under way
  - blocking_findings: The blocking findings the last inventory recorded, each {path, code, message}
  - warning_count:  How many modules the last inventory reported a warning for
  - branch_import_count: How many modules import something absent, but only inside a branch
  - undefined_script_count: How many published Scripts their own module does not define
  - reports_excluded: Whether the last inventory reported built-in report modules it excludes
- helper_count:   How many modules the last inventory reported would publish nothing
  - rows:           One {key, name, project, revision} per Project either pass named, project None until staged
  - run:            The open MigrationRun, or None before the first staging pass
  - cutover_job:    The most recent cutover Job, or None
  - cutover_queued: Whether a cutover is already under way
  - can_cut_over:   Whether the crossing has not been recorded yet and can be served past the fence
  - cutover_interrupted: Whether the state reached cutover with the crossing unrecorded, so the fence may have closed
  - unservable_projects: The staged Projects that could serve nothing past the fence, each {project_key, reason}
  - activation_job: The most recent activation Job, or None
  - activation_queued: Whether an activation is already under way
  - can_activate:   Whether the fence has been crossed, which is activation's only precondition
  - references_job: The most recent reference pass Job, or None
  - references_queued: Whether a reference pass is already under way
  - can_repoint:    Whether every migrated Project that still exists serves, so a reference has a row to name
  - projects_not_serving: The migrated Projects that exist and serve nothing, which a reference pass would refuse over
  - cleanup_job:    The most recent cleanup Job, or None
  - cleanup_queued: Whether a cleanup is already under way
  - can_clean_up:   Whether every reference step is done and every mapped Project serves, which is what deletion waits for
  - verification_job: The most recent verification Job, or None
