improve UI design for better contrast, colors and layout

[River-Mochi]

Issue

• no contrast in the colors makes it hard to find the drop-down and sections
• organize for usability

Proposal

• add box frame around the drop-downs sections to show them
• simplify names of sections. no need to say Select, just lock the Update button so if not every section has something, then Update stays unclickable.

1. See mock image design
2. Put all selectors in a row
3. Make UPDATE button larger with a color like green
4. Does Egui allow use of Fontawesome icons in the app? is that where folder icon comes from?
5. move INFO messages to the right of [UPDATE] which gives lot of room if Info message is longer.
6. this leaves all Logs at the bottom for cleaner user interaction.
   

Option 1, just one idea I have. other possibilities too to help organize the screen so it's visually pleasing and easier for the user to follow for UI and UX.

Option 2 Next image adds Pinecil Connected function conveniently to left of the Update button. [Pinecil is connected] or [Pinecil is not connected.]

A mate made this mockup for me, this is what the end goal will be
