Known bug: abort controller logic doesn't work properly in firefox
because a general network error is fired before the abort callback.
We would probably need to track the navigation-click event to overcome
this.

* Introduce a queue to exclude contention between tasks while chartjs is
updating charts/animating views.
* Fix a bug where chart updates triggered by interval timeout
aren't stored in the SessionStore.
* Reinit all charts instead of reusing old chart objects when switching
between raw data and smoothed data views. This avoids issues with
buffered/stale state, which led to charts rendering incorrect data in certain cases.
* Pull uptime informatin from the systree endpoint.

Adds a web-based user interface with a live dashboard for displaying system metrics. The metrics are coming from Mosquitto's HTTP API.
UI is written using basic web stack (HTML, CSS, and JS) without the use of the frameworks. All the dependencies (chartjs, chartjs-plugin-zoom, hammerjs) are stored in the `src/lib` directory. CSS classes generated with tailwind are in src/styles.css. The idea is to be able to serve the UI by starting a simple http server from dashbard/src/.
This UI can be further extended by adding additional web pages.
