Keep the Orca Cloud Agent Tests Out of the System Keychain

The display-name tests call set_user_session(), which persists the session.
The agent they built was in keychain mode, so every run saved a fake
OrcaSlicer/Auth session into the system keychain of whoever ran the tests,
replacing their real Orca Cloud login on any desktop with a working keychain.

Move them next to the other agent tests and build the agent the same way:
encrypted-file mode with a throwaway config directory.
