fix(hosted-rooms): local_profiles skips the profile-delete tombstone dir

`hermes profile delete` leaves `profiles/.deleted/<name>` behind.
`HostedRoomService.local_profiles()` fed every subdirectory name to the
roster, so `.deleted` failed `validate_roster`'s identifier check and
`plan_next_task` raised on every cycle for every room until the
directory was removed by hand (#106847, bug 2). Skip dot-dirs and
tombstoned profiles, using the same `named_profile_is_deleted` predicate
`hermes_cli.profiles` uses to list live profiles.
