Start moving Volunteer Profile to separate /profile[/:userId] route and begin datafetch/styling

[alanchangxyz]

Right now the volunteer profile is

• hardcoded into the volunteer heatmap page on admin (which we do not want)
• only programmed to fetch data for a hardcoded volunteer user id 1.

We need to

• move it to a separate route for showing the volunteer profile (/profile[:userId] according to the routes doc)
• change the backend call to fetch it for any volunteer ID (or the current user ID if userId is not provided)
• style it to match the figma

Let's just try to make as much progress on this as possible for this milestone (I am available for reinforcement after finishing #138 if you need it)
