fix(screenshots): dashboard screenshots do not capture filter state

[fisjac]

SUMMARY

When downloading a Dashboard as image or Export to PDF, the filters applied to the dashboard are not considered in the downloaded/exported file.

To fix this, I've pulled the relevant slices of dashboard state from the redux store and attached them to the screenshot request payload.

TESTING INSTRUCTIONS

Create a Dashboard with a table using the vehicle sales dataset with the date column.

Apply any dashboard Time filter (Time Grain filter → year)

Publish your changes.

Click on the three ellipses > Download as image or Export as PDF
