Avoid status probes during circuit discovery

[liudger]

This pull request simplifies and streamlines the detection logic for available heating circuits in the BSBLAN integration. The main change is that circuit discovery now relies solely on the configured probe parameters (operating mode), no longer querying or interpreting status parameters. The test suite is updated to reflect this logic, removing tests and code related to status parameter checks and ensuring that only the correct probe parameters are used.

Circuit discovery logic simplification:

• src/bsblan/bsblan.py: The get_available_circuits method now only uses the operating mode probe parameters (700 for circuit 1, 1000 for circuit 2) to detect available circuits, eliminating the previous two-step check involving status parameters. This makes setup lighter and avoids false negatives when status data is unavailable. [1] [2]

Test suite updates:

• tests/test_circuit.py: All tests are updated to remove status parameter probes and checks. Tests now assert that only the operating mode parameters are queried, and that circuits are detected solely based on these probes. [1] [2] [3] [4] [5] [6]
• tests/test_circuit.py: Tests previously covering scenarios where status parameters returned inactive or empty results are removed or refactored, as these cases are no longer relevant to circuit detection. [1] [2]

These changes improve reliability and maintainability by making circuit detection logic more predictable and easier to test.

Pull request overview

This PR simplifies heating circuit discovery in python-bsblan by determining available circuits solely via the operating mode probe parameters, removing the previous status-parameter-based validation step to reduce setup overhead and avoid false negatives.

Changes:

• Updated BSBLAN.get_available_circuits() to probe only operating mode parameters (no status probes).
• Removed status-probe scenarios from the circuit discovery tests and added assertions that only probe parameters are queried.
