SHS-6056: Allow external access to Localist API methods

[codechefmarc]

READY FOR REVIEW

Summary

• Changes some of the methods in the LocalistUrlWidget so they are public to be able to be accessed from outside the widget and adds a $base_url parameter that can be passed by the external calls.
• This work was needed for SHS-6056: Dashboard: Importer block: Events SU-HSDO/suhumsci#1755 which needed to provide Localist importer information into the dashboard. We felt that we wanted to reuse code where possible.
• For future work - it would be suggested to move all the Localist specific methods into their own service which could be called by the widget and by other services like the dashboard block.
