Core: Post-KivyMD cleanup 2 and enhancements (#4876)

* Adds a new class allowing TextFields to be resized
* Resizes most CommonClient components to be more in-line with pre-KivyMD
* Change the color of SelectableLabels and TooltipLabels to white
* Fixed ClientTabs not correctly showing the current tab indicator
* The server label now features a (i) icon to indicate that it can be hovered over.
* Changed the default `primary_palette` to `Lightsteelblue` and the default `dynamic_scheme_name` to `VIBRANT`
* Properly set attributes on `KivyJSONToTextParser.TextColors` so that proper typing can be utilized if an individual value is needed
* Fixed some buttons being discolored permanently once pressed
* Sped up the animations of button ripples and tab switching
* Added the ability to insert a new tab to `GameManager.add_client_tab`
* Hovering over the "Command" button in CommonClient will now display the contents of `/help` as a popup (note: this popup can be too large on default height for adequately large /help (SC2 Client), but should always fit fine on fullscreen).
* Fixed invalid sizing of MessageBox errors, and changed their text color to white
