fix(macmini): mount prometheus config directly so /-/reload picks up edits

Browse source 
VictoriaMetrics + vmalert previously copied prometheus.yml/alerts.yml from
/mnt/prometheus-config/ into /etc/prometheus/ at container start. The copy
silently drifted from the host file whenever the container wasn't restarted —
which is exactly what hid the matrix/element removal from status.mana.how
until 2026-04-08, when VM was still actively scraping the deleted targets
because its in-container config snapshot pre-dated the cleanup.

Now both containers mount ./docker/prometheus directly into /etc/prometheus
(resp. /etc/alerts) read-only and point the binary at it, and deploy.sh
issues POST /-/reload to both after each deploy so config edits go live
without a container recreate.
