Eduard Iten 8467b3e347 feat: Make valve obstacle detection parameters configurable via settings and shell
This commit introduces configurable obstacle detection thresholds for the valve, allowing them to be set and persisted via the Zephyr settings subsystem and controlled through the shell and Modbus tool.

- `software/lib/valve/Kconfig`: Added new Kconfig options `VALVE_OBSTACLE_THRESHOLD_OPEN_MA` and `VALVE_OBSTACLE_THRESHOLD_CLOSE_MA` for compile-time configuration and default values.
- `software/include/lib/valve.h`: Removed hardcoded defines and added API functions for setting and getting obstacle thresholds.
- `software/lib/valve/valve.c`:
    - Updated `valve_work_handler` to use the new configurable obstacle thresholds.
    - Integrated loading and saving of obstacle thresholds via the settings subsystem in `valve_init`.
    - Implemented the new setter and getter functions for obstacle thresholds.
    - Updated the `LOG_INF` message in `valve_init` to display the new obstacle threshold values.
- `software/apps/slave_node/prj.conf`: Added default values for the new Kconfig options.
- `software/lib/shell_valve/shell_valve.c`: Added new shell commands `valve set_obstacle_open` and `valve set_obstacle_close` to modify the obstacle thresholds, and updated `valve show` to display them.
- `software/tools/modbus_tool/modbus_tool.py`:
    - Defined new Modbus holding registers (`REG_HOLDING_OBSTACLE_THRESHOLD_OPEN_MA`, `REG_HOLDING_OBSTACLE_THRESHOLD_CLOSE_MA`).
    - Updated `poll_status` to read these new registers.
    - Modified the `main_menu` to include "Set Obstacle Open" and "Set Obstacle Close" options in the settings menu, allowing users to view and modify these parameters.
- `software/lib/modbus_server/modbus_server.c`:
    - Updated `holding_reg_rd` to read the new obstacle threshold registers.
    - Updated `holding_reg_wr` to write to the new obstacle threshold registers.
    - Removed incorrect `REG_HOLDING_END_CURRENT_THRESHOLD_OPEN_MA` and `REG_HOLDING_END_CURRENT_THRESHOLD_CLOSE_MA` cases from `input_reg_rd`.
- `software/include/lib/modbus_registers.h`: Created a new header file to centralize Modbus register definitions, which were previously hardcoded in `modbus_tool.py`.

Set the current threshold in milliamps for obstacle detection
during valve opening. If the motor current exceeds this value,
an obstacle is detected and the valve stops.

Set the current threshold in milliamps for obstacle detection
during valve closing. If the motor current exceeds this value,
