CloudflareDDNS.update() was calling the wrong endpoint; fix to use the
correct zone-records API so DDNS updates actually land.
NoIP and FreeDNS providers now return explicit "not implemented" errors
instead of silently claiming success, preventing false-positive health state.
PicNgoDNS ACME dns-challenge now sends the token in the request body (was
missing), so cert issuance no longer silently fails.
add_peer gates builtin-service provisioning on the installed-services list
so a freshly-provisioned peer does not attempt to configure services that
aren't present, eliminating the startup error loop.
Startup Caddyfile regeneration added to routes/config.py so that a stale
on-disk Caddyfile no longer triggers the health-monitor restart loop after
a config change.
