- Created `test_relay_chn_tilt_multi.c` and `test_relay_chn_tilt_single.c` to implement comprehensive tests for the tilt functionality of relay channels, covering various scenarios including transitions between states and sensitivity settings.
- Introduced a new partition table in `partitionTable.csv` for proper memory management.
- Updated `sdkconfig` to set the relay channel count to 1 for single channel testing and adjusted related configurations.
- Added default configuration file `sdkconfig.defaults.single` for streamlined testing setup.
Break down tests into categories to improve maintainability and test granularity. This makes it easier to execute unit tests in CI/CD pipelines.
Closes #1054.
