fix(status-page): point at vm.mana.how (GPU-Box VM) instead of localhost:9090

After Phase 2c VM moved off the Mini, but the status-page generator
still queried localhost:9090 — and Colima containers can't reach the
GPU-Box's LAN IP through the Mini's bridge. Result: status.mana.how
showed 0/0 services UP across the board.

Routed VM through a new vm.mana.how Public Hostname on the
mana-gpu-server tunnel (config v24) so the Mini-side container reaches
it the same way browsers do. /api/v1/query path is identical, no
script changes required. Network-mode no longer needs to be host now
that the URL is public.

Verified live: status.json reports 49/53 services UP.
