Add Zoom to AoI Button

[lossyrob]

Overview

This PR adds a button to the map that zooms to an AOI if one exists.

Connects #3242

Demo

If there is not an AOI set, the button is hidden on the map:

Once an AOI is selected, the button shows up on the bottom right of the map:

Here's what happens when you press it:

Notes

I implemented analogous entries for the SidebarToggleControl control everywhere I found it, as I believe that gave the best coverage for where the new control needed to be referenced (tests, settings, compare map). However a second look on what other areas of the app should be considered from someone with broader knowledge would be great!

Testing Instructions

• Notice there is no button on the initial page
• Select an AOI
• Notice the button with the target icon; hover over to confirm correct tooltip
• Zoom to somewhere that isn't centered on the AOI
• Press the button: You're back!
• "Change area" to clear the AOI. No more button!

Tested it out, works great. Will take a look at the code shortly.

This works well. Left some minor comments on the code, mainly having to do with style and convention.
