hermes: boot-persistent quadlet units for the gateway, dashboard, and webui

The trio ran as bare compose containers and died silently at the Aug 26
reboot — nothing restarts compose containers at boot. Each now has a
boot-persistent unit (WantedBy=default.target; the v1 quadlet generator on
this host cannot enable generated units). The deploy handler retires the
compose-era containers only while the units are not yet active, then
(re)starts each unit.

Units run the image under a localhost/hermes-agent:latest alias tag (the
quadlet create path on this host cannot resolve registry-prefixed refs from
local storage); the deploy handler tags first. The gateway's :8090 publish
is dropped — nothing consumes it; the public vhost now routes to the
dashboard's login-gated UI on 9119.

+# Unit name: hermes-webui.service (container name: hermes-webui)
+#
+# Runs the open-source hermes-webui (github.com/nesquena/hermes-webui) in
+# foreground mode: bootstrap.py creates .venv inside the mounted checkout,
+# installs WebUI + agent deps, then execs server.py as a single foreground
+# process. It reads HERMES_HOME=/data, so it drives the SAME agent state
+# (memory, skills, sessions) as the gateway container. Loopback-only publish:
+# the SSH tunnel (phone -> Dankclaw:22) is the sole ingress. The password
+# gates Hermex logins and lives in the host .env (git-ignored).
