add address search to map

[alenastern]

Add leaflet address search to map - should be a 1-line addition per this example!

Hi Alena,

Happy to add this. Two quick clarifications before I implement:

Geographic scope: Should the address search be available at all geography levels (State/County/Tract)? For County and Tract views this is straightforward. For the State view, the shifted geometries complicate this since address coordinates won't align with the displayed polygons - we'd need to decide whether to disable search at State level or handle the coordinate mismatch.

User flow: What should happen after a user searches an address? Should the map:

1. Pan to that location and display the underlying geography's data?
2. Auto-select that geography in the dropdown (if it's not already selected)?
3. Just pan to the location without changing the selected geography?

This will help me set up the reactive logic correctly with the existing geography selection system.

Since this feature is a nice-to-have and not part of the MVP, I would also like to leave this issue for a later fix. Let me know if you'd like me to prioritize it instead.
