Closes#14716
Closes#14717

Adds a new user-scoped tailnet API endpoint (api/v2/tailnet) with a new RPC stream for receiving updates on workspaces owned by a specific user, as defined in#14716.

When a stream is started, theWorkspaceUpdatesProvider will begin listening on the user-scoped pubsub events implemented in#14964. When a relevant event type is seen (such as a workspace state transition), the provider will query the DB for all the workspaces (and agents) owned by the user. This gets compared against the result of the previous query to produce a set of workspace updates.

Workspace updates can be requested for any user ID, however only workspaces the authorised user is permitted toActionRead will have their updates streamed.
Opening a tunnel to an agent requires that the user can performActionSSH against the workspace containing it.

ctx isn't used anywhere, so it andcancelFn are superfluous, which I think makesClose() on this superfluous.

The intention was forsub to store a context who's parent isupdatesProvider's context, so that callingClose on the updates provider closes all the existing subscriptions - will fix.

This needs to be thec.peerCtx ---coordCtx is the context of the Coordinator's lifetime.

You should add a test that adds a subject to a context you use to callCoordinate() and verify the subject is there on theAuthorize call. Same test for the AGPL implementation.

This was actually passing without, but it would take the entire 10 seconds. Interestingly, the PGCoord doesn't have this behaviour

Yeah, PGCoord is more aggressive with closing things down, forcibly booting anything still connected because it has contexts plumbed thru for background tasks like heartbeats. The AGPL coordinator is considerably simpler and has no coordinator-scoped context.

A few nits inline, but I don't need to review again
