matrix: swarm-controller is the only minter

Every hive is in a swarm and every swarm runs matrix, so every swarm has a
swarm-controller, and since #4810 its hive_sender pass mints each hive's
@hive-<hive>: sender token into the store every five minutes. The two
other minters of that token go:

- swarm-matrix-ctl mint: the systemd.services.swarm-matrix-ctl unit in the
  hive-matrix container, Command::Mint and src/mint.rs. The binary, its
  appservice render/publish verbs, ctlPackage, ctlActive and the ctl cert
  role stay. bao-matrix-reader's checks on the deleted unit are removed;
  the leaf-identity and no-token-in-env checks now look at
  swarm-matrix-appservice-publish, which runs under the same identity.
- the hive-side mint ladder in hive-c0re's ensure_hive_user
  (register/appservice-login/password-login with the local as_token), with
  read_appservice_token, paths::matrix_appservice_token and the helpers
  only it used. ensure_hive_user now takes the store's token, keeps the
  file when the store has none or can't be reached, and fails otherwise.
- hivectl matrix sync-admin: the verb, HostRequest::MatrixSyncAdmin and
  handle_matrix_sync_admin. The periodic MatrixSweep (ensure_all) is
  unchanged apart from no longer reading the local as_token.

This removes the double-mint race #4810's review flagged: two minters
logging in on one pinned device could leave a dead token in the store
until the next pass.
