Ben Barclay 80f8ffc74c fix(dashboard): pin machine-dashboard reroute to the machine root, not $HOME/.hermes (#46487)
The unified machine-dashboard reroute (cmd_dashboard) re-execs a named-profile
dashboard launch as the machine dashboard and dropped HERMES_HOME from the
child env with the comment "so the child binds the machine root". That holds
for a standard install (root == ~/.hermes) but breaks the Docker layout: the
published image sets `ENV HERMES_HOME=/opt/data`, so once HERMES_HOME is unset
the child falls back to $HOME/.hermes = /opt/data/.hermes — an empty,
auto-seeded home.

Two user-visible symptoms, one root cause (reported via support):

1. Dashboard Profiles page shows only an empty `default` — the real
   default/oracle/saga profiles live under /opt/data/profiles, but the
   rerouted child resolves _get_profiles_root() to /opt/data/.hermes/profiles.

2. The "Update Hermes" button runs `hermes update` inside the container
   repeatedly instead of bailing with the docker-update guidance. The Docker
   guard keys off detect_install_method(), which reads
   $HERMES_HOME/.install_method; the image stamps that at /opt/data, but the
   misresolved home has no stamp, no HERMES_MANAGED, and no .git → falls
   through to "pip", so the guard never fires.

The reporter's workaround was to bind-mount the host dir at both /opt/data and
/opt/data/.hermes so the two paths converge (at the cost of a self-referential
recursion).

Fix: resolve the machine root explicitly with get_default_hermes_root() and set
it on the child env instead of popping HERMES_HOME. That helper returns the
root for both layouts — ~/.hermes for a standard install, and /opt/data for
Docker (it strips a trailing profiles/<name>). Falls back to the old pop
behaviour only if root resolution raises, so the reroute is never blocked.

Regression tests in test_dashboard_unified_launch.py: the existing standard-
install test now asserts the child carries HERMES_HOME == get_default_hermes_root()
(not absent), and a new test_reexec_pins_docker_machine_root covers the Docker
layout (HERMES_HOME=/opt/data/profiles/oracle → child gets /opt/data). Both
fail against the pre-fix pop behaviour (mutation-verified).
