Minor Pattern Viewer Overhaul

[amy-corson-ibigroup]

Description:

• Remove the hideBackButton prop (it didn't do anything)
• Pattern viewer back button on by default (because switching between patterns means you can't use the browser back button to return to route viewer)
• Trip viewer back button on by default (intuitive to return to the itinerary)
• Other back buttons fully removed
• Created a back button component that can be used in several places

Also I removed the background color on the pattern viewer and changed the route color into more of an accent color. I also moved the operator and external link to the bottom of the page (in line with some previous designs) but I am open to feedback.

• Removed the route color background
• Created a RouteRowDetails component that can be used in the route viewer and pattern viewer

PR Checklist:

• Does the code follow accessibility standards (WCAG 2.1 AA Compliant)?
• Are all languages supported (Internationalization/Localization)?
• Are appropriate Typescript types implemented?

Overall this is quite a good cleanup. Well implemented. Just a few small issues!

However, I would like to maybe ask for the old colored background mode to be configurable (even if off by default)? Just because on some configurations which have a whiter map the amount of white on the screen is pretty glaring, especially when the nearby view sidebar, the itinerary selection sidebar, and schedule view sidebar each have strong background colors.

This is awkward -- the line when it is loading

Seeing this when clicking a route from the route viewer. As the pattern viewer is loading
