Rebase and test commit afe66af, "refactor: combine ward filtering onto map page"

[KyleDolezal]

Overview
This issue tracks work to merge a refactor into main, including addressing merge conflicts and testing functionality.

Problem
Commit afe66af, part of branch create-ward-filtering, was not merged in during a recent attempt to merge several commits to main. Difficulties in addressing merge conflicts led us to hold off on merging this commit in order to invest dedicated time to researching and testing it.

Solution

• Cherry-pick the commit on top of main.
• Address any merge conflicts
• Test the functionality

Update

• I cherry-picked the commit on top of main.
• Merge conflicts have been resolved.
• I checked in 5965ec to address compilation errors.
• I tested the functionality and identified outstanding issues:

1. The route map consists entirely of yellow lines, and hovering turns them white.
   
2. The more stats page does not function properly.
   
3. The modal for an individual route is not styled correctly.

Analysis

• The commit consists of: moving functionality around, adding styles, and updating the formatting of existing code.
• The commit, when merged in, is not expected to add to or impact existing functionality.
• Fixing the functionality for the commit may not be a trivial undertaking, as there are multiple issues with the code change.

Next steps
I recommend:

• Storing the rebased commit (including fixes to address compilation errors) on a branch here.
• Documenting issues with the code change in this issue.
• Creating a new issue to fix outstanding problems with the code change.
• Closing this issue and prioritizing the new issue appropriately.
