Add device-command mapping for treadmill inclination overrides and preserve logical selection on lossy feedback

[cagnulein]

Motivation

• Provide an option to control the physical device command value associated with each legacy raw/index row while keeping existing logical inclination override behavior by default.
• Preserve the logical inclination chosen by the app when some treadmills report lossy or imprecise raw feedback after issuing a mapped outbound command.

Description

• Introduces outbound-device-command mapping APIs: treadmillInclinationDeviceCommand, treadmillInclinationOverrideForRawFeedback, and updates treadmillInclinationOverrideReverse to return device-command values when configured, and to remember/apply logical selections while awaiting/validating feedback.
• Adds state fields to treadmill (m_mappedInclination*) to track mapped rows, awaiting feedback and the last reported raw value, and adds parseInclinationOverride to use new feedback-aware mapping.
• Adds settings keys and defaults for treadmill_inclination_override_device_command_* in qzsettings.h/cpp, increments settings counts, and exposes them in the UI by updating settings-treadmill-inclination-override.qml, settings.qml and settings-catalog.json (new controls and a repeater for raw rows).
• Replaces legacy calls to the basic override in several device parsers to use the new feedback-aware functions (treadmillInclinationOverrideForRawFeedback / parseInclinationOverride) and adds unit tests (TreadmillInclinationOverrideTest) and test wiring to validate mapping and feedback behavior.

Testing

• Added Google Test unit tests in tst/Devices/TestTreadmillInclinationOverrides.cpp and header, and registered them in the test project file; test suite exercises legacy reverse mapping, custom device-command mappings, and feedback preservation logic.
• Ran the test suite including TreadmillInclinationOverrideTest and the updated tests under the test harness; the new tests passed.
