test: Update integration tests for driver abstraction refactor

Updated tests to reflect the new driver-based architecture where GATT
server and connection management are handled by the driver layer instead
of directly in BLEInterface.

Changes:
- test_integration.py: Updated to check for driver callbacks instead of
  old GATT server methods (_data_received_callback vs on_data_received)
- test_integration.py: Added test for driver abstraction layer
- test_prioritization.py: Updated to check for driver.connect() instead
  of removed _connect_to_peer() method

All 106 tests now pass (excluding test_refactor_suite.py which has
import issues and appears to be obsolete).
