Update to match the Seq 4.0 API

[nblumhardt]

This PR brings the client in line with the Seq version 4 API, matching the server version to follow 4.0.28-pre. (This code will not work correctly against the 4.0.28-pre version).

Besides added features, the following breaking changes should be noted:

• Pins have become Permalinks, and the related types/members renamed accordingly
• Watches are completely gone, replaced by Dashboards

@andymac4182 build 4.0.0-dev-00045 plus Seq 4.0.50-pre should cover all of the new API surface area. Let me know if you encounter anything missing from the client library.

One little thing to note - charts can support multiple SQL queries under the hood, and each query multiple alerts, but the UI will currently only provide an editor for the first query and alert per chart. (Some more goodness coming in a near-future release :-).)

Update - the build will be 4.0.51-pre - just found an annoying issue, CI kicking off again :-)

Thanks! Looking forward to this.
