point the state and feature moderation call sites at the sdk

Query, notification and feature-level moderation reads switch to the sdk types
and take their `moderate*`/`hasMutedWord` entry points from the
`lib/moderation/subjects` seam, since these paths still carry
`@atproto/api`-typed views.

`shouldFilterNotif` is the one behavioral seam worth noting: its notification
and facet values come from an unmigrated read, so the mute-word check goes
through the widening wrapper rather than the sdk export directly.
