fix(catalyst): chroot EventSource auth via access_token query param — unblocks 13 cloud list views (#1074)

The chroot Sovereign Console SPA performs its own PKCE OIDC flow with
Keycloak and stores the access_token in sessionStorage. installFetchAuthInterceptor
patches window.fetch to attach Authorization: Bearer to /api/v1/* calls
— but the EventSource browser API does NOT support custom request
headers. The chroot also has no PIN-minted catalyst_session cookie
(operator authenticates via Keycloak, not PIN), so withCredentials:true
sent nothing. Result: every /api/v1/sovereigns/<id>/k8s/stream connection
landed in 401 → SPA rendered "Stream temporarily unreachable". Affected
tests: TC-066 services, TC-067 ingresses, TC-071 pods, TC-072 deployments,
TC-073 statefulsets, TC-074 daemonsets, TC-075 replicasets, TC-076
configmaps, TC-078 namespaces, TC-079 nodes, TC-080 persistentvolumes,
TC-081 endpointslices, TC-086 pods.

Fix follows the standard SSE auth pattern used by Grafana / Loki:
accept the access token as a `?access_token=<jwt>` URL query parameter,
validate it through the same JWKS path as Authorization: Bearer.

BE — products/catalyst/bootstrap/api/internal/auth/session.go:
ReadSessionToken now consults three channels in order: (1) Authorization:
Bearer header, (2) ?access_token=<jwt> query parameter, (3) catalyst_session
cookie. Same JWT-shape (3 base64url segments) sanity check before
ValidateToken so a malformed value short-circuits to 401 with no JWKS
round-trip. The query-param path NEVER displaces the header when both
are present (header wins) — preserves the live-fetch source of truth
when an old ?access_token= is left in the address bar after a refresh.

BE — products/catalyst/bootstrap/api/cmd/api/main.go:
Replaced chi's middleware.Logger with a custom pathOnlyLogFormatter
(implementing chi's middleware.LogFormatter) that emits r.URL.Path only
— never r.RequestURI. Critical for credential hygiene per CLAUDE.md §10:
chi.DefaultLogFormatter writes RequestURI verbatim, which would leak
the access_token query parameter to stdout. The new logger emits
structured slog fields (method/path/status/elapsedMs/remote) instead.

FE — useK8sCacheStream.ts + useK8sStream.ts:
Both EventSource consumers now read loadTokens() from sessionStorage and
append `&access_token=<accessToken>` to the URL when an OIDC token is
present. Mother (Catalyst-Zero) sessions store no OIDC tokens, so the
param is omitted and the existing catalyst_session cookie path is unchanged.

Tests:
- 8 new Go tests in session_test.go covering all 7 channel
  permutations + JWT-shape validation + whitespace handling.
- 2 new vitest cases in useK8sStream.test.ts asserting the URL contains
  access_token=<jwt> when sessionStorage has an OIDC token, and omits
  it on mother (cookie-only path).

Verification:
  $ go build ./... && go test ./internal/auth/... → ok
  $ npm run typecheck && npm run build → ok
  $ npx vitest run src/lib/useK8sStream.test.ts → 11/11 passing
  $ curl -i 'https://console.omantel.biz/.../k8s/stream?kinds=pod' → 401
    (will return 200 + SSE frames after deploy)

Risk surface: a stale ?access_token= URL in the operator's address bar
will be rejected with 401 once the JWT expires, surfacing as the same
"Stream temporarily unreachable" banner. The SPA's existing reconnect
loop drives a fresh EventSource on every retry, which picks up the
freshest token from sessionStorage — so the failure mode is self-healing
on the next browser-driven retry.
