#2967 - Enhance AirSpace simulation with dynamic environment and bandwidth/channel management

This commit introduces several key enhancements to the AirSpace class, improving the realism and configurability of the wireless network. Major additions include the AirSpaceEnvironmentType and ChannelWidth enums, dynamic adjustment of interface speeds based on environmental settings, and comprehensive bandwidth management features. Additionally, the software now supports configuration of channel widths via the config file, incorporates accurate SNR and capacity calculations, and enforces bandwidth limits more effectively across wireless interfaces. Updated tests ensure that the new functionalities integrate seamlessly with existing systems.
