Both submodules now support self-service personal access tokens (PATs) for
calling the management API without an OIDC browser session. Document the
feature in README.md + docs/ (mint under "API Tokens" in each UI, use as
`Authorization: Bearer sso_…` / `prx_…`, authenticates as the creator with
their permissions, rotate/revoke in the UI, persists in Redis via AOF).
Bump gitlinks to the merged submodule tips:
- sso-manager-node: 6920a9f -> b91ef27 (PR #35)
- proxy: 8e78604 -> a9a48c3 (PR #119)
