refactor: tables V2

[ClementTsang]

Description

A description of the change and what it does. If relevant (such as any change that modifies the UI), please provide screenshots of the change:

Overview

This PR generally refactors the table and sortable table components, used by temp, disk, process, and CPU widgets.

Note most of the commits in this PR are going to be more of trial and error/testing things out, rather than proper commits. I'll probably squash some things as this approaches completion.

General goals

This PR started with the following goals in mind:

• Reduce memory usage - the previous refactor seemed to increase memory usage by a significant amount, so hopefully this refactor knocks that down a peg.
• Make using sortable tables (and tables in general) a bit less ugly - ton of gross hard-coding required to get it to just work last time, so hopefully something more elegant can come out of this.

Other

• This PR also fixes a longstanding bug in disk or temp tables, where you could select the last value of one of those tables, and if you removed a value (e.g. unmount a drive), the scroll index would be incorrect. This is easily fixed by doing a check during the draw to ensure data is consistent with state.
• Moves colour scheme creation before app creation in the main.rs pipeline. Highly considering moving it into the config pipeline in the future.
