This PR adds the new API key scope feature for workspace agents to restrict access to user-specific data. Key changes include:
- Adding an api_key_scope field in the Agent proto, database model, and terraform resource.
- Integrating the new field into middleware (AgentAPIKeyScopeCheckMW) for access enforcement.
- Updating audit logs and documentation to reflect the new API key scope attribute.

Needs to bump the provisionerd API version, since it adds a new (backward compatible) field.

I would like to see some additional tests around the RBAC scope, but I don't need to review again after that.

heads-up: there are a number of in-flight PRs that will be bumping this field.

Since the 1.5 version has yet to be released, I don't think I need to bump it again (?).

No, just giving a heads-up of a potential need to rebase.

I had to rebase anyway since six new migrations happened, and new fields were added to the agent, too.

Thisseems like the right way to do this if I recall correctly but it does make me nervous that we're essentially saying "this scope can do anything at site level except read user data". I'd like to see a test case added that confirms that this scope can't do things that the actual auth subject can't do.

It is an intersection with the roles.

LG, really like seeing the scopes have some utility!

If this is only used once, we can probably go back to doing it inline, rather than declaring it up here.
Just a nit

Add API Key Scope Restriction for Workspace Agents
This PR adds a new security feature that allows workspace agents to have restricted API key scopes. It introduces a new
api_key_scopefield to workspace agents with two possible values:all: Full access to all endpoints (existing behavior)no_user_data: Restricts access to user-specific data endpointsThe implementation includes:
api_key_scopecolumn to theworkspace_agentstableapi_key_scopeattributeThe scope restrictions have been applied to several endpoints that expose user data:
/external-authendpointsThis change allows administrators to create workspaces with agents that have limited access to sensitive user data, improving security in multi-agent environments where some agents may need to be more restricted than others.
