[WIP] LF-4691: UI to connect to ensemble

[SayakaOno]

TODO: Delete unused files and code

Description

• Add Partners component (to be renamed to Addons or something similar later)
  • The position of the cross icon for clearing error is off - this will be fixed in another ticket
• Update PostSensor container
  • API integration (POST farmAddon, GET sensors)
  • Remove white background colour from the form (Loïc confirmed!)
• Add translations and colours (Includes translations and colours for LF-4693 and 4696 🙏)
• Make Loading component fixed relative to viewport (The file is currently nested within ContextForm, but I plan to extract it in a future PR. Keeping it for now to avoid a bigger diff)
• Implement ability to hide Previous button in WithStepperProgressBar
• Add isCompactSideMenu prop to POST_SENSOR_URL route
• Update Map component
  • Navigate to the Add sensors form when "Sensor" is selected
  • Remove sensor upload related code
• Update ContextForm to accept formMode prop ("onBlur", "onChange" etc.)
