resolve_client_location() enforces ownership (sound location in one of the
client's active projects) and 404s everything else — same response for missing
and not-yours, so location existence never leaks. active_unit_for_location()
resolves the currently-assigned SLM.
Scoped GET /portal/api/location/{id}/live and /history: gate -> resolve unit ->
read SLMM cache (never the device). /live returns a SCRUBBED projection (sound
metrics + run state only; no battery/SD/raw_payload). Both degrade gracefully
when there's no device or SLMM is down.
Verified: ownership gate (owns / other-client / vibration / deleted-project /
removed / nonexistent) + active-vs-completed unit resolution — 8/8 on a temp DB.

backend/portal_auth.py: stdlib HMAC-signed session cookie carrying the access-
token id (re-validated against the DB each request, so revoke kills live
sessions), hash_token, resolve_token, and the get_current_client dependency
(raises PortalAuthError). SECRET_KEY env (insecure dev default + warning).
routers/portal.py: /portal/enter/{token} mints the cookie -> /portal; /logout;
/access; /portal home stub. main.py registers the router + a PortalAuthError
handler (HTML access page for pages, 401 JSON for /portal/api/*).
Portal shell templates (base, access_required, overview stub), branded dark.
Verified: cookie round-trip + tamper/garbage rejection, token resolution
(valid/bad), get_current_client (valid/no-cookie/revoked) — 8/8 against a temp DB.
