flip the preferences and labeler reads to sdk types

`UsePreferencesQueryResponse` now derives from the sdk's `BskyPreferences`
rather than the legacy one, which removes the cast the previous slice put on the
assembled response - the query already returns the sdk action's result, so the
two now type structurally.

`labeler.ts`'s three service reads move to the appview client and return
`app.bsky.labeler.defs` views, because `interpretLabelValueDefinitions` takes
the lexicon-typed view. `moderation-opts.tsx` reads `Client.appLabelers`
instead of `AtpAgent.appLabelers`: the lex static is already branded, so the
fallback labeler list satisfies `ModerationPrefsLabeler` without a cast.

`MutedWords` follows the prefs types: `expiresAt` is a `DatetimeString` now,
built with `toDatetimeString` rather than `Date.toISOString`, and
`sanitizeMutedWordValue` comes from `@bsky.app/sdk/utils`.
