Slack command/API to (re)trigger reporting for a specific org/site and audit type

**Is your feature request related to a problem? Please describe.**
I'm always frustrated when there is a bug in the reporting and we cannot retrigger the reporting for a specific org/site and audit type that was impacted.

**Describe the solution you'd like**
API to (re)trigger reporting for a specific org/site and audit type

**Describe alternatives you've considered**
Double reporting for all customers
Retriggering the internal reporting and manually notify post the results to impacted customer.

**Additional context**

**Asks that could have been solved by the feature**

Start by reading src/handlers/reports.js in the spacecat-jobs-dispatcher repository and the linked Slack discussion for the reporting flow and affected use case. Trace how reporting currently runs, then define the API or Slack entry point needed to target one org/site and audit type. Done means the selected reporting can be retriggered without rerunning reports for all customers.
