repoint the last AtpAgent statics and drop the dead conversions

Five sites read `AtpAgent.appLabelers`, which the previous commit stopped
populating - a silent regression, since an empty static reads as "no
authorities" rather than failing. All now read `Client.appLabelers`, the static
that is actually configured:

- `lib/moderation.ts`'s `isAppLabeler`, which decides whether a labeler is
  non-removable in the UI;
- `preferences/moderation.ts`'s `useMyLabelersQuery`, which seeds the labeler
  list with the app authorities;
- `feed/custom.ts`'s hand-rolled logged-out `getFeed`, which reproduces the
  header lex would have emitted because the request bypasses the client.

`sessionAccountToSession` (the `AtpSessionData` conversion) had no callers left
once the bridge agent went, and the age assurance config read - the one
standalone `new AtpAgent` the age assurance slice deliberately left behind -
moves to the public appview client, which is what it was approximating.

That is the last `AtpAgent` in src. What remains of `@atproto/api` in the
session layer is types and `BSKY_LABELER_DID`, which S4d owns.
