zeekayandGitHub 5ed75779e8 fix(auth): migrate login worker /api/* → canonical /v1/iam/* (HIP-0111) (#1)
* corona→corona: academic Corona now only in lp-220-p3q-corona

* chore: restore upstream attribution + NOTICE (OSS compliance)

* auth: migrate front-door worker IAM calls to canonical /v1/iam/*

Every IAM-targeted path the hanzo.id/lux.id/zoo.id/pars.id front-door
worker emits now uses the canonical /v1/iam/* surface (HIP-0111), off the
legacy /api/*, /login/oauth/*, and bare /oauth/* shapes. Proven against
the IAM router: PathRewriteFilter collapses /api/<ep>->/v1/iam/<ep> and
the oauth aliases ->/v1/iam/oauth/<ep>; every target route exists.

Emitted-path changes (worker.js):
- inline login JS:  /api/get-app-login->/v1/iam/get-app-login;
  social ->/v1/iam/oauth/authorize; password+web3 ->/v1/iam/login
- inline signup JS: get-app-login, social ->/v1/iam/oauth/authorize;
  web3 ->/v1/iam/login; /api/signup->/v1/iam/signup
- inline forgot JS: get-app-login; /api/send-verification-code
  ->/v1/iam/send-verification-code
- platform+MPC IAM callback token exchange: /api/login/oauth/access_token
  ->/v1/iam/oauth/token
- /oauth/{token,introspect,revoke,userinfo,logout} public facades now hop
  to /v1/iam/oauth/{token,introspect,revoke,userinfo,logout} internally
- /callback social handler: /api/login->/v1/iam/login
- provider-aware authorize handler now matches the canonical
  /v1/iam/oauth/authorize (and legacy /login/oauth/authorize), targets
  IAM /v1/iam/oauth/authorize, keeps the _oauth_ctx cookie + branded page
- /logout: /api/logout->/v1/iam/logout

Kept (worker public contract; IAM canonicalizes inbound): the worker own
/oauth/* facade routes, the OIDC discovery rewrite, and IAM_PATHS legacy
inbound tolerance. Untouched (separate concern, flagged): the github.com
platform OAuth bridge.

Verified per brand (hanzo/lux/zoo/pars) with Playwright network
interception against worker.js under workerd (wrangler dev, local):
login renders -> password POST hits /v1/iam/login -> Google button
-> /v1/iam/oauth/authorize?provider=provider-google; zero /api/* and
zero bare /oauth/authorize across the session. /oauth/token facade probe
returns IAM token-endpoint JSON (invalid_client), proving the
/v1/iam/oauth/token hop is live. 36/36 + 7/7 checks pass.
