This commit adds a new event subscription task in HomeModel, one which
streams low volume but important filters from NostrDB.
This was done to address an issue where the contact filters in the
general handler task could yield too many notes from NostrDB, hitting
its limits and clipping off important events such as mute-lists, leading
to downstream issues such as unintended mute-list overrides.
This issue was not present since the last public release, therefore no
changelog entry is needed.
