mautrix-twitter: expose bridge HTTP API (for mautrix-manager and similar)

Route the whole mautrix-twitter HTTP port via Traefik under
`<matrix-fqn>/bridges/twitter` and populate the existing
appservice.public_address, reusing the matrix_bridges_exposure_*
mechanism. The provisioning shared secret is already auto-generated in
group_vars, so the provisioning API is enabled.
