Significant UX changes and bugfixes.

• Fixed critical bug with initial PLY support (texture coordinates / UVs now import correctly) (@michaelt919).
• It is now possible to import a Metashape project directly into Kintsugi 3D Builder without separately exporting cameras and a mesh out of Metashape (@Andersoni0723, @denneyl2711).
• The image of the calibration target used for tone calibration is saved and persists after closing and reopening the project (@Bluepeltz12, @michaelt919).
• Fixed a bug that caused issues when re-entering light calibration task after previously completing it and setting the light calibration to a value other than (0,0) (@michaelt919).
• Fixed a bug where the loading bar would disappear before loading was finished (@michaelt919).
• Fixed a bug where clear cache would not work if files in the cache had a file extension in all caps (@michaelt919).
• Various UX changes and miscellaneous bugfixes (@denneyl2711, @Shadoshi26, @Isaac-tesch, @michaelt919).
