Feature: Add “Continue” button and badge for selected path

[davidha99]

Because

A user might get confused about the current behavior of the "Resume" button in All Paths (#3230, #4495).

This PR

Helps to differentiate a selected path from the rest by:

• Adding a "Selected" badge to the currently selected path.
• Keeping only one "Continue" button instead of "Resume" and "View" buttons to selected path.

Note: User needs to be logged in.
