Add organization members page

[perryr16]

• Members page to update or delete org users
• fetches and formats access level tree
• creates a reusable error handler that accurately passes backend error messages to the frontend via an error service
• general tweaks

All of the backend error responses come in as

{ status: 'error', message: 'some descriptive error message' } 

This should reduce a lot of duplicate code and make service catchErrors much simpler going forward

I'm getting a warning in console when I open the member modal:

NG0956: The configured tracking expression (track by identity) caused re-creation of the entire collection of size 1. This is an expensive operation requiring destruction and subsequent creation of DOM nodes, directives, components etc. Please review the "track expression" and make sure that it uniquely identifies items in a collection. Find more at https://angular.dev/errors/NG0956

I think if you update form-modal's iterator for accessLevelInstance to track by ali.id instead of ali it will fix the issue.

Otherwise, this looks good, glad you pulled the table out to a component, and the error service is a really good idea!

Pending the fix for that NG0956 error, this looks good to me.
