OIA-241: pin httpx2 + authlib for imio.omnia.core OAuth2 support

[duchenean]

Companion to IMIO/imio.omnia.core#2 (OIA-241).

versions.cfg only:

• Add httpx2 = 2.7.0, authlib = 1.7.2, httpcore2 = 2.7.0.
• Override idna = 3.18 (httpx2 needs >=3.18, above the Plone 6.1 KGS pin of 3.11).
• Keep httpx = 0.28.1 for now with a TODO — droppable once the imio.omnia.assistant release without its unused httpx dependency is pinned here (DELIBE-322 tracks the wider sweep).

Summary by CodeRabbit

• Chores
  • Updated dependency documentation with clearer “required by” relationships for HTTP/authentication components.
  • Pinned the idna version more explicitly to match the related HTTP constraint.
  • Added a TODO note indicating the httpx pin can be removed in a future release when it’s no longer needed.
