Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

The "search for user or group" search box only lets you filter users by e-mails because the q parameter of the underlying API that this calls (/api/v2/templates/<..>/acl/available?q=<user>) only filters for the "email" field out of all these fields:

{
  "id": "...",
  "username": "...",
  "name": "...",
  "avatar_url": "...",
  "email": "...",
  "created_at": "2024-07-23T14:40:20.205142Z",
  "updated_at": "2025-12-02T22:02:43.589182Z",
  "last_seen_at": "2025-12-02T22:02:43.589182Z",
  "status": "active",
  "login_type": "github"
},

I believe at least username and name (display name) should be queried too, maybe id too.

Steps to Reproduce
