The one-time import of a pre-0.1.7 `settings.yaml` section never ran. It
started from the `ctx.inject(['settings'], …)` callback, which fires the
moment the settings SERVICE appears — while the loader is still mounting
rows, so `describe()` does not list this plugin's own entry yet, the lookup
returns undefined, and the import bailed on "no form" without a trace.
Upstream's own migration waits (`ctx.root.loader.await()`); this does the
same.
That made every early return of the import invisible, which is how it went
unnoticed: the callback simply produced nothing. It now returns a named
outcome ('imported' / 'no-profile-home' / 'no-form' / 'already-configured' /
'no-legacy-section' / 'rejected') and the caller logs it — anomalies at warn,
the rest at info. The `loader` mirror's `await` is optional so a composition
without the cordis loader still reaches the import instead of aborting the
whole settings face inside the inject callback; the smoke fakes model it.
Verified on the live 3080 instance: after the upgrade the settings form
reports the user's real values back (autoOpenJobs false, workspaceFence
false, the nine-entry tabsEnabled map), where before it reported pure
defaults. The mount lane stays 7/7.
