Refactor unit preferences and update chart components

* Refactor user settings to use enum for unit preferences (temperature,
network, disk).
* Update chart components to utilize new unit formatting functions
* Remove deprecated conversion functions and streamline unit handling
across charts.
* Enhance settings page to allow user selection of unit preferences with
updated labels.
