fix: param nesting for report creation requests (closes #658)

[Justintime50]

Description

The params were not nested at the root level for report creation which is required so params like columns and additional_columns were not accepted at the API. This PR corrects the nesting to put them at the root which should fix these params when generating reports. (closes #658)

Additionally, un-nested all cassette files. Years ago we tested this lib against multiple frameworks at once which required multiple sets of cassettes which is no longer the case. The cassettes nested in a net folder is no longer helpful, moving them up a level.

Finally, cleaned up a similar problem with webhooks that lingered from years earlier where to avoid collisions, we had to differentiate the urls used in webhook generation based on net version in use. Removed that as a part of this too.

Testing

Re-recorded all affected cassettes (otherwise cassettes just moved location).
