I estimate this ticket at a 3 for moving over a good amount of relatively simple elements over to components.

TO DO: @jilladams split out V1 work to new ticket

Should this also change: https://va.gov/boston-health-care/health-services/?

Nevermind, I see there's another ticket for that.

Due to #17807 popping up, where adoption of components ran into some browser-specific styling issues, I've added ACs here to cover cross-browser verification.

tl;dr: let's use mobile emulator to test lower envs on desktop, and verify on phones in prod.
