ReportContent: add ?commentId support (#1826)

## Ticket
1822

## Changes
- Add `?commentId=` support in the URL.
- `claimId` remains a required parameter so that we can derive the comment URL.
    - The backend will know it's a comment report when both parameters are present.
- The comment URL is added to the top of `additional_details`.
- The backend rejects if `additional_details` is provided for DMCA. Grayed out DMCA for the case of reporting comments.
