Allow data-lake variables to auto trigger actions

To be merged after #1674
Fix #1641

Still reviewing code, but for now, there is an UI issue:

• Change the save button text color to white (1)

[ES-Alexander]

The actual triggering seems to work, but:

• There's no description of the link functionality in the help text at the top
  • e.g. "Actions can be run manually, or configured to trigger automatically when a linked Data Lake variable changes"
• Dropdown is light themed (and so are the others in the Actions section), while the rest of the interface uses dark ones:
  
• Variables aren't searchable, so you need to scroll for ages to find what you're looking for
• Configured variables can't be removed from in the bar, so they need to be found again
  • Each selected pill should ideally have a little x on the right for removing it

As something of a side note, it's hard to test using actual values, because they can't be set manually, and #1542 means sliders seemingly can't be used for integer values, and #1678 means dials aren't usable for PWM values and the like :(

Will fix all the raised points.

Yeah...
I need to add that functionality for adding/removing variables and persist them, but while that, try this branch, as it adds the hardcoded variables for the camera.

It works very well.
But is it possible to set a value or a range for that data lake variable to trigger the action? If not, could it be implemented on this PR?

For example, if water temp goes above 28º C, trigger the action that let some cold water in.

I think it can fit here, yes. Let me give it a try!
