Dragan Spiridonov c72bbc15dd fix(auth): close /api/field bypass, two fail-opens, and a self-disarming test
Findings from a qe-court adversarial round (4 prosecutors across 2 vendors).
Each was verified against the code before being accepted; the ones below
reproduced, the rest are reported in the PR thread rather than acted on.

FATAL — `/api/field` was reachable with no credential, on both listeners.
The gate protected `/api/v1/*` by prefix. `/api/field` is the REST sibling of
`/ws/field` and serves the same signed FieldEvent stream — live presence, pose,
vitals. `/ws/field` was gated in this PR; its twin one path segment over was
not. Measured with RUVIEW_API_TOKEN set and no credential supplied:

    /api/v1/models  401      (control)
    /ws/field       401      (gated by this PR)
    /api/field      200      on :8080 AND :8765

Fixed by inverting the gate to deny-by-default with an explicit anonymous
allowlist (`/`, `/ui`, `/health`, `/oauth/`). A route added at a new path is
now gated because nobody exposed it, rather than exposed because nobody
protected it — the same inversion already applied to the scope gate.

FATAL — the wiring test disarmed itself exactly when it mattered.
`Server::start` returned an Option that all five tests turned into `return`,
so a server that failed to boot produced "5 passed" with zero assertions run,
and cargo swallows the skip line without --nocapture. The one test that
observes real wiring — the guard against both shipped bypasses — was silent
for any change that breaks startup, including a boot panic in the auth path.
It now panics with the child's stderr.

MAJOR — a malformed client-id list silently disabled the audience check.
An empty allowlist is the opt-out sentinel in verify.rs. `RUVIEW_OAUTH_CLIENT_IDS=","`
is non-empty, passes the guard, then filters to an empty Vec — turning the
audience boundary off with no log and admitting a token minted for any other
Cognitum product. Only a literal `*` may opt out now; anything else that parses
to nothing warns and falls back to the default. Same fail-open shape as the
scope denylist this PR already had to invert.

MAJOR — credentials were world-readable for a window on every refresh.
`fs::write` creates at 0666 & !umask (0644 by default), and both writers
chmodded afterwards. The existing permissions test asserted on the FINAL file
and passed throughout. Affected the CLI refresh token (rotated with reuse
detection — a thief who presents it first takes the session family) and the
browser session secret (the HMAC key for every session; stealing it forges any
account at any scope). Both now create with mode 0600 via OpenOptions.

MAJOR — ui/sw.js cached authenticated API responses.
Closing the /oauth/ leg left the /api/ leg open. `networkFirst` cached every
successful response, keyed by URL alone, purged by nothing at sign-out: sign in
as A, load sensing data, sign out, sign in as B, lose the network, and B is
served A's data with no authorization check. API responses are now network-only
— which is also the correct behaviour for a live sensing dashboard, where
replaying a stale reading can show a room occupied after the person left — plus
a cache purge on sign-out.

CI — 40 of ruview-auth's 87 tests never ran.
The workspace runs --no-default-features, which switches off the `login` and
`pkce` features. Measured: 47 tests vs 87. The whole interactive sign-in path —
credential storage, single-flight refresh, the file lock, the loopback callback
— was green locally and never executed in CI. Added an --all-features step.
(Checked the sensing-server for the same problem and did NOT find it:
bearer_auth's 49 and browser_session's 15 do run under CI flags.)

Tests: +2 wiring tests (one fails against the old gate with
"http port served /api/field to an anonymous caller", passes after), +3 UI
service-worker tests, +3 CLI scope tests, +1 temp-file permission test, +1
client-id parsing test. wifi-densepose-cli/src/auth.rs had zero tests and
builds its own scope string, so the library's least-privilege test said nothing
about what the CLI requests.

Verified: ruview-auth 61+25+2 pass (--all-features), sensing-server bearer_auth
50, browser_session 15, auth_wiring 7, workspace 25 suites clean, UI 22.
