code cleanup

Alerts suppressed by an active maintenance window were being correctly
muted in the notification pipeline but appeared as state=active in the
v2 GetAlerts response, since MaintenanceMuter.Mutes had no marker
side-effect (unlike inhibitor/silencer).

Add MaintenanceMuter.MutedBy returning the matching window IDs, and
plumb a mutedByFunc callback through NewGettableAlertsFromAlertProvider
into AlertToOpenAPIAlert. The upstream v2 API forces state=suppressed
when mutedBy is non-empty, so the frontend's existing state-based
rendering picks it up without further changes.

Use the dedicated mutedBy field rather than SilencedBy to avoid
violating the "complete set of silence IDs" contract that anything
querying silences by ID would rely on.
