Run the housekeeper for a single member, optionally retroactively

Add a "Hausmeister für dieses Mitglied" button to the member view. It
runs every rule scoped to just that member -- e.g. after editing a
contribution override or payment frequency, to recompute their claims on
demand instead of waiting for or triggering a full run over every
member. A checkbox lets the board force retroactive claim creation for
just that one run, without changing the application-wide default
setting.

Housekeeper.run() gained member_id and retroactive_claims parameters.
Scoping to one member skips the asset checks and leaves every other
member's tasks completely untouched, since their rules never ran this
pass and so fall outside the resolved-scope set that
_resolve_stale_tasks uses to decide what to clear.
