Asset API sorting by name is case-sensitive, causing test failures

[Ahmad-Wahid]

The AssetAPI:index endpoint sorts asset names case-sensitively.

Because of this:

• "Test wind turbine" sorts before "incineration line" in ascending order.

Existing tests assumed case-insensitive ordering, which caused two failures in test_get_assets when sorting by name.

The API behavior is consistent, but test expectations are incorrect.
