Add query execution indicators

[danield137]

Shows a native running indicator while Kusto queries execute.

Also adds last-run details to the query CodeLens: run time, duration, and a copyable client request ID.

Validation: npm run lint/test/compile, dotnet build.

Pull request overview

This PR adds end-to-end support for query execution UX improvements in the VS Code extension: a native “running” indicator while queries execute, plus richer “last run” metadata (timestamp, duration, and client request ID) surfaced via CodeLens and persisted in history. It also wires a clientRequestId through the client → language server → Kusto connection stack so executions can be correlated.

Changes:

• Add query-running UI state (editor title command + CodeLens “Running” + status bar item + progress notification) driven by a new msKustoExplorer.queryRunning context key.
• Persist and display last-run details (started-at timestamp, client-measured duration, and client request ID), including a “Copy CID” CodeLens action.
• Plumb optional clientRequestId from the client LSP request through server query execution to Kusto ClientRequestProperties.ClientRequestId.
