fix: Sync user guide to correct workflow section (#2592)

Resolves https://github.com/webrecorder/browsertrix/issues/2560

## Changes

- Syncs workflow current form section with user guide section.
- Stickies "User Guide" button to top of viewport so that user guide can
be opened.
- Makes content behind user guide clickable (fixes issues with stickied
elements shifting when user guide is not contained to the parent
element.)
- Decreases size of user guide text when embedded in an iframe.
- Refactors overflow scrim to reuse CSS variables.
