refactor: Refactor memory_usage module to use module config. (#515)

Also addresses a number of bugs:
- the percent sign not displaying correctly on some terminal emulators, including kitty
- changing the symbol in the configuration file didn't do anything
- swap being shown even if the system didn't have any
