[PM-12740] Move CollectionAdminService to AC Team

[eliykat]

🎟️ Tracking

https://bitwarden.atlassian.net/browse/PM-12740

📔 Objective

Move CollectionAdminService and related files to AC Team ownership.

This also moves it out of the web app and into libs/admin-console/common. This facilitates its likely reuse in other clients (particularly CLI) and also separates it from client-specific code. This also necessitated the creation of an abstract interface for it.

The main change for most codeowners is updated import statements.
