fix(desktop): keep named-profile desktop backends per-profile (#44510)
Desktop spawns its dashboard backend with `--profile <name>` and
`HERMES_DESKTOP=1`. cmd_dashboard's unified-launch routing treats any
named profile as a request for the shared machine dashboard: it re-execs
as the default profile (dropping HERMES_HOME) or, when one is already
listening, prints "Machine dashboard already running ... Managing profile
'<name>'" and exits 0. Either way the desktop-spawned child exits before
the app sees a ready backend, so Desktop retries forever — the Windows
named-profile boot loop in the post-mortem.

Skip the machine-dashboard reroute when HERMES_DESKTOP=1 so desktop pool
backends stay per-profile (which is what the pool expects). Carved out of
#44478.

"""Tests for the unified profile→machine dashboard launch routing.
`<profile> dashboard` routes to ONE machine-level dashboard instead of
spawning a per-profile server: attach (open browser at ?profile=) when one
is already listening, else re-exec as the machine dashboard with the
launching profile preselected. `--isolated` opts out.
