Interface rework

[MaximeHollebecq]

This pull request is created to solve the issue #3 , the different scene were reworked to fit with the mockup in the issue except the connecting + error handling screen because the database connection status are displayed on the main screen.

• After entering your credential (Email , arduino COM port , baudrate) , you can click on the connect button. an error message will be displayed if the COM port/Email is wrong.

• when the credentials are correct , you are redirected to the main scene where you can click on the start button to start the logging and enable the display

• when you want to stop the logging , you have to press the stop button , an explorer panel will appear which make you choose the destination of the csv files that contain the data

• if needed , a restart logging button is available in case you want to restart the process

Should I review the code ?

@QuentinDaveau yes please, have @MaximeHollebecq walk you through it and provide some feedback. That would be great, thanks! 🌴

The commits and code seem all good to me, it's Quentin's approuved :D! We spotted a small issue with the data logging however, but it is out of context of this pull request. Maxime should create an issue for it.
