Add basic survey feature support

[aaronbrethorst]

This is the first plan for designing the survey feature in WayFinder.

Overview

• Two survey types (like in Android):
  1. Popup survey.
  2. Survey triggered when a user clicks on a stop.
• In WayFinder, clicking a stop will show a popup asking if the user wants to take the survey.
• Use browser local storage to prevent the survey from appearing multiple times for the same user.

Components

• Will use Flowbite Svelte for form elements (checkboxes, radios, inputs, etc.).

Could you take a look and let me know if this looks good or if you’d like to change anything?
