fix: linting and JS errors due to paragon modal deprecation pr

[adamstankiewicz]

Description

A PR was merged a few days ago with several linting issues, many of which would result in JS errors. These changes were released to production about 8 hours ago. We are seeing these errors creep up in New Relic reporting, preventing critical user flows.

This PR ensures all linting errors are resolved for this project, resolving those code paths with possible JS bugs due to missing Spinner imports.

For all changes

• Ensure adequate tests are in place (or reviewed existing tests cover changes)

Only if submitting a visual change

• Ensure to attach screenshots
• Ensure to have UX team confirm screenshots
