Fix ngx-bootstrap vulnerability

[mjtravers]

The ngx-bootstrap has an XSS vulnerability: https://app.circleci.com/pipelines/github/fecgov/fecfile-web-app/169/workflows/bcad3ac5-e317-4c95-a216-fe2fa42befbf/jobs/652

The vulnerability looks to be how the typeahead is being used. Fix the XSS issue for the typeahead either by using the ng-bootstrap library (also in use) has may have a better implementation of typeahead or by escaping data before use in the ngx-bootstrap typeahead.

Stretch goal: It'd be nice to have only one angular bootstrap library dependency, so while in the code, evaluate the level of effort to move the site entirely into ng-bootstrap

Acceptance Criteria
Snyk does not report a XSS vulnerability in its report.

This issue is no longer relevant as ngx-bootstrap has been removed from the app during the work preformed for issue #156.
Closing ticket.
