refactor: atlas-admin-api service COMPASS-10893

[paula-stacho]

Description

Main change: Moves the logic related to Atlas Admin API to a dedicated service (the original code introduced in #8262 - unfortunately the git diff isn't quite clear on what has been just moved 🙈 )

Other notable changes:

• the connectionString -> cluster & project mapping is expensive to get and immutable - the service adds a cache (cleared when the user logs out from atlas - I wasn't sure if we need that, but it feels cleaner - we can reevaluate later when we have more functionality depending on it)
• added versioning - this is not very well documented in the atlas admin api docs, some more info is on the public docs - each resource/endpoint can have it's own version, but the one used for default appears to be the closest to a latest "stable"

Note: this is dead code at the moment but I tested the atlas log in + cluster state request with a dummy code.

Pull request overview

This PR introduces a new @mongodb-js/atlas-admin-api package and wires it into Compass (desktop + web) and the assistant plugin via a shared provider/locator pattern, aiming to centralize Atlas Admin API access.

Changes:

• Added the new @mongodb-js/atlas-admin-api workspace package (service, provider/locator, pagination/types utilities, tests).
• Wrapped existing Atlas providers with AtlasAdminApiServiceProvider in Compass, Compass Web, and the shared testing-library wrapper.
• Updated Compass Assistant to consume the new Atlas Admin API service via app-registry injection.
