Improve monitor channel handling by adding support for quoted values

- Introduced `strip_optional_quotes` function to handle monitor channel values with optional surrounding quotes.
- Updated `load_monitor_channels` method in `CommandManager` to utilize the new function, ensuring compatibility with quoted and unquoted channel configurations.
- Modified `generate_samples` function to apply the same logic for consistency.
- Added tests for `strip_optional_quotes` to validate behavior with various input cases.
