[PATCH 0/2] access: add OpenID Connect support for #4281

[Azharul Haque <haque@azharul.com>]

The native Flutter "Proxmox VE Companion" app never implemented OpenID
Connect / OAuth realm login (bug #4281[0]): selecting an OAuth realm
just showed username/password fields that could never work.

This series adds the API-layer building blocks for OIDC login:

  - a `type` property on PveAccessDomainModel, needed to detect
    OpenID realms in the login UI
  - helpers for PVE's /access/openid/auth-url and /access/openid/login
    endpoints

A companion series to proxmox_login_manager builds the login UI and
OAuth flow on top of this, and a companion series to
pve_flutter_frontend wires up the Android-side callback activity.

Verified end-to-end against a real PVE server with an Authentik OIDC
realm, on both Android and iOS.
