Add Reporting web page

[hayk96]

Is your feature request related to a problem? Please describe.
As the application already has an API for exporting data from Prometheus in multiple formats, this feature needs to be made available on the web.

Describe the solution you'd like
Build a web page, "Reporting Page," where users can type their PromQL, provide necessary attributes like times, field names, etc., and export the required data by accessing everything that the /export API provides.

Describe alternatives you've considered
