Add UserExtraInfo (avatar + mail) to the WOPI CheckFileInfo response for
authenticated, non-public-share users.
UserExtraInfo format (per Collabora SDK):
https://sdk.collaboraonline.com/docs/advanced_integration.html#userextrainfo
```json
{
"avatar": "http://url/to/user/avatar",
"mail": "user@server.com"
}
```
After this change, CheckFileInfo returns:
```json
{
"BaseFileName": "Pedro-filled-hazcom.docx",
"UserFriendlyName": "Admin",
"UserId": "346364...39323030",
"UserCanWrite": true,
"UserCanRename": true,
"IsAdminUser": true,
"EnableInsertRemoteImage": true,
"EnableInsertRemoteFile": true,
"EnableOwnerTermination": true,
"UserExtraInfo": {
"avatar": "https://host:9300/wopi/avatars/{userID}?access_token={wopiToken}",
"mail": "admin@example.org"
},
"PostMessageOrigin": "https://localhost:9200",
"message": "CheckFileInfo: success"
}
```
Avatars are served via a new /wopi/avatars/{userID} endpoint on the
collaboration service, authenticated by the WOPI token. The endpoint
calls the Graph service directly (bypassing the proxy) using the reva
access token via x-access-token header.
All tests pass:
go test ./services/collaboration/... ./services/graph/... ./services/proxy/...
