[management,client] Gate remote jobs behind an admin opt-in with MDM support (#7153)

This introduces a disabled-by-default allow-remote-jobs setting that
controls whether the management server may run jobs (such as debug
bundles) on a peer. The flag propagates end to end: through client
configuration, the daemon SetConfig and Login requests, authentication,
and system info, up to management, where it is stored on the peer and
exposed on the peers API as remote_jobs_allowed. The client refuses any
management-requested job unless the peer has opted in. Because enabling
remote jobs crosses the user-to-root boundary, turning it on requires
privilege, mirroring the SSH-server gate. Administrators can enforce the
setting through MDM policy on both macOS and Windows, and MDM can also
override the debug-bundle upload URL. The change ships policy
documentation and generated profile templates, and adds configuration,
conflict, and enforcement tests covering the opt-in, privilege, and MDM
paths.
