Anso 86bfc108ae fix(security): resolve open CodeQL path-injection and temp-file alerts (#1322)
Re-establish the path-containment barrier inline at the backup readdir
sink in restoreStackFiles. The sink previously built backupDir through
the getBackupDir helper, whose stack-name validation the static analyzer
does not trace, leaving a flagged path-injection sink. The barrier now
resolves backupDir against its root and asserts containment inline, the
same pattern already used in backupStackFiles. Behavior is unchanged for
valid stack names (already validated one line above by resolveStackDir).

Scope the js/insecure-temporary-file rule out of e2e/** in the CodeQL
config. End-to-end fixtures must seed files into the backend's COMPOSE_DIR
so the API under test can read them back; that path is a fixed location
under /tmp in both CI and local dev, which the rule flags. A randomized
temp directory does not apply because the backend resolves against its own
COMPOSE_DIR. Production code is still analyzed.

Anso d882f223f4 feat(api-tokens): switch to sen_sk_ prefixed opaque keys (#1062)
* feat(api-tokens): switch to sen_sk_ prefixed opaque keys

Replace JWT-shaped API tokens with 56-char opaque keys of the form
`sen_sk_<43-char base62 random><6-char base62 checksum>` (256-bit
entropy, sha256-truncated checksum). Node-proxy tokens stay JWTs.

Why:
* The api_token path was already a sha256 DB lookup; the JWT signature
  was wasted work and the 400d JWT ceiling vs DB expires_at was a
  confusing dual bound.
* Opaque tokens carry a verifiable checksum so malformed/typoed values
  are rejected before any SQLite lookup.
* `sen_sk_` prefix is recognizable to GitHub, TruffleHog, GitGuardian
  and makes the on-wire shape visually distinct from node_proxy JWTs.

Changes:
* New `utils/apiTokenFormat.ts` (generate + checksum-verify, CSPRNG via
  randomInt, timingSafeEqual on the checksum compare).
* `middleware/auth.ts` and `websocket/upgradeHandler.ts` route opaque
  tokens before any jwt.verify; 401 messages unified to avoid a
  token-existence oracle.
* `middleware/rateLimiters.ts` short-circuits opaque tokens in the
  node_proxy detection and keys per-token via a non-reversible sha256
  slice so each token keeps its own bucket without a DB hit.
* All six existing tests migrated from jwt.sign({scope:'api_token'})
  to generateApiToken(); new format-only test suite covering prefix,
  length, alphabet, checksum reject paths, and a 10k-iteration
  collision/integrity loop.
* Docs (features/api-tokens.mdx, api-reference/overview.mdx) describe
  the shape and drop the obsolete JWT-ceiling note.

* fix(api-tokens): clear CI lint and CodeQL false positives

* Drop unused TEST_USERNAME import in remote-console-session.test.ts;
  the migration to generateApiToken() left it orphaned.
* Add a CodeQL barrier model so `generateApiToken`'s ReturnValue does
  not flow into the `insufficient-password-hash` query. The function
  emits 256-bit CSPRNG opaque keys; sha256 of the raw token is the
  correct construction for high-entropy API tokens (bcrypt-class
  hashes target low-entropy human passwords). CodeQL's name heuristic
  was treating "Token" as a password source and flagging the standard
  sha256 wrapping at all 9 call sites.

* ci(codeql): exclude js/insufficient-password-hash for token paths

The previous barrierModel data extension was a no-op for this rule: the
js/insufficient-password-hash query identifies its "password" sources via
SensitiveExpr's name heuristic ("token", "secret", "key" substrings),
which is upstream of the taint-tracking layer where barrierModel applies.
Verified by post-push re-analysis: 9 alerts still open, all undismissed.

Replace the dead extension with a path-scoped query-filter in
codeql-config.yml so the rule no longer fires on apiTokenFormat,
apiTokens, and the test directory. Real user-password hashing code
elsewhere in the repo (auth, users, setup routes) remains analyzed.

The 9 existing alerts on PR #1062 are dismissed via API as false
positives with a justification pointing at this config. Future runs
will not re-flag them because of the path filter.

Anso 0dcf309c48 fix: add CodeQL barrier model for sanitizeForLog against log injection (#935)
sanitizeForLog() already strips CR, LF, and control characters from user
input before logging, but CodeQL did not recognize the custom sanitizer.
This caused false-positive log-injection alerts at every call site.

Add a CodeQL data extension model that marks the return value of
sanitizeForLog() as a barrier against log-injection taint, and a
codeql-config.yml that references it.
