KRATOS 6e0a665118 fix(auth): propagate credentials to every provider-build surface and pin children to the live provider (#366)
* fix(auth): propagate credentials to every provider-build surface and pin children to the live provider

Sub-agents, swarm members, ACP sessions, and mid-run escalation switches
could build providers without the credentials the parent was running with.
This consolidates credential resolution so every surface gets the same auth:

- Wrap deps.newProvider once in fillAppDeps to fold the stored API key in
  centrally; ACP, exec escalation, and buildProvider no longer patch it
  per call site (an apiKeyStored profile previously went out keyless on
  those paths and 401'd).
- Export ZERO_PROVIDER at startup (buildProvider) and keep exporting on
  every runtime switch (wizard, onboarding, /model, /provider), so spawned
  children resolve the parent's live provider instead of whatever another
  process last persisted to config.json. Injected via appDeps so tests
  never mutate the process environment.
- Share one OAuth login selection end to end: ProviderProfile.
  OAuthLoginCandidates (name, then catalog-ID fallback; nothing for a
  profile with its own configured credential) + oauth.FirstStored resolve
  the login ONCE, and the bound store key is threaded through
  providers.Options.OAuthLoginKey so the Codex account-id header always
  reads the same login that issued the bearer token. A renamed profile
  (name != catalog ID) now finds its login; an explicit API key is never
  silently overridden by a same-name or catalog-shared OAuth login.
- Export ProviderProfile.HasConfiguredCredential as the single "profile is
  key-authed" predicate (cli/tui/config previously had three copies).
- applyProviderWizard commits live state (provider, profile, name, env
  export) only after BOTH the build and the config persist succeed, so a
  persist failure no longer leaves the chat running on a provider the
  status line and children disagree with.

Covered by red-green tests for each path: stored-key wrap, escalation
switch, catalog-ID fallback (incl. case-variant names), explicit-key
protection, same-login account selection, wizard persist-failure rollback,
onboarding/startup env export.

* test: isolate OAuth/config test storage and fix the flaky MCP response-id test

Review + CI fixes, all test-only:

- factory/cli OAuth tests: pin ZERO_OAUTH_STORAGE=file next to the temp
  ZERO_OAUTH_TOKENS_PATH — an inherited "keyring" value sends NewStore to
  the OS keychain and ignores the temp path entirely, so the tests could
  read (or clobber) the developer's real logins. newOAuthStoreForTest now
  owns both pins so a future call site can't forget them.
- TestApplyProviderWizardExportsActiveProviderEnv: point m.userConfigPath
  at a temp config and stub newProvider, so the SUCCESS path exercises the
  full build+persist+commit sequence in isolation (the default empty path
  silently skipped persist; a changed default must never reach the real
  user config).
- TestClientRequestWaitsForMatchingResponseID (ubuntu smoke flake): the
  responses were pre-loaded into a bytes.Buffer, so the client's reader
  goroutine could consume the matching response — and hit EOF — before
  request() registered its pending id, failing with "request() error =
  EOF" on fast runners. The fake server now sits on pipes and responds
  only after reading the outgoing request, matching production ordering;
  survives -race -count=50.
