Monitor partner card: onboard phase indicator per remote host

vv_partner_state() now reads setup.db and adds onboard_phase (0/1/2/null)
to each host entry.

Partner card JS renders a badge under the hostname for remote hosts that
haven't completed Phase 2: amber "Awaiting onboard" (phase 1) or grey
"Not provisioned" (phase 0). Phase 2 complete shows nothing extra.
