This PR improves the portal's internal link detection logic to be more
robust when handling empty or undefined configuration values.
Previously, the code could fail when `customDomain` was empty, causing
external links to incorrectly behave as internal links. The fix
introduces a new `isSameOrigin` helper function that safely compares
URLs using proper URL parsing and origin comparison, gracefully handling
edge cases like missing domains, relative paths, and malformed URLs.
This ensures external links consistently open in new tabs regardless of
portal configuration completeness.
Due to the pattern `**/specs/*.spec.js` defined in CircleCI, none of the
frontend spec in the folders such as
`specs/<domain-name>/getters.spec.js` were not executed in Circle CI.
This PR fixes the issue, along with the following changes:
- Use vitest instead of jest
- Remove jest dependancies
- Update tests to work with vitest
