Correct band frequency ranges

Channel frequency ranges for the three bands (2.4G, 5G, and 6G) are used
in different places with separate definitions or via literal numbers.
Also, the values are not accurate and sometimes not consistent.

This commit uses definitions and utility methods created in ScanResults.
