Attu fails to show collection data with CollectionReadWrite role

[kish5432]

Describe the bug:
I have configured RBAC in Milvus by granting DatabaseReadWrite and CollectionReadWrite privileges to a role and attaching this role to a user. These privileges are granted on a non-default database.

When I log in to Attu using this user:
The non-default database is visible
All collections under the database are listed

However, the collections appear empty in Attu (no data shown)

If I access the same database and collections using an admin/superuser or via SDK, the collections are present and contain data.

This seems to be an issue with how Attu handles RBAC permissions for collections in non-default databases.

Steps to reproduce:

1. Create a non-default database in Milvus
2. Create collections and insert data into the non-default database
3. Create a role and grant the following privileges on the non-default database:
   DatabaseReadWrite
   CollectionReadWrite
4. Attach the role to a user
5. Log in to Attu using this user
6. Select the non-default database
7. Open any collection

Attu version:
2.5.12

Milvus version:
2.5.13
