placeholder - refactor front end to remove SaaSType enum

[adamsachs]

Is your feature request related to a specific problem?

With #1197, we removed the SaaSType enum from the backend, and made the type field on SaaS configs fully dynamic. The frontend still contains a static SaaSType enum that should be removed to reflect the dynamic nature of SaaS config types accordingly. According to @chriscalhoun1974 , there's some nontrivial refactoring work that needs to be done on the frontend codebase to make this possible. This issue is a general placeholder to account for that work so that we don't lose track of it - more specific issues can be created as the refactoring work is better defined.

#1230 and #1231 are backend features that are likely needed in order to make this frontend refactoring possible.

@chriscalhoun1974 please feel free to update this as you see fit!

Additional context

• Likely blocked by automate copy of saas logo images to front-end directory #1230 and update connection_type endpoint to include encoded logo image data in response payload #1231.
• Generally part of an effort to make the frontend more robust/dynamic in its handling of SaaS connector types
