Ettore Di Giacinto c5f636d1b9 refactor(addons): move connector file bytes by handle only ...

A connector add-on no longer carries file bytes in the connector
envelope. The ops media and send_file need a transfer handle, and the
gateway refuses a call to them without one, or for a kind that declares
no files.

- The manifest field files.transfer, the inline file of a request and
  of an answer (ConnectorFile) and the 1 MiB cap
  (MaxConnectorFileBytes) are removed. The 2 MiB limit of a connector
  call between hosts drops to 1 MiB, because it holds text and no file.
- A kind that declares no files moves no file: the host answers a sender
  who attaches one with a plain sentence and does not offer attach_file.
  A direction left out of a declared files block still gets the host
  ceiling.
- The inline layer is gone from the file limit, from the API
  (inline_bytes) and from the Files section of the connector page.
- The Telegram and Slack add-ons keep only the streaming paths. The
  tests moved to the handle path, and the studio test rig gives every
  connector add-on a table of handles.
