fix: ui design of the share button in the in-progress report and various other UI issues.

[raktima-opensignlabs]

1. declined document popup hiding the navigation menu in mobile view
2. add loader to load animation of send request
3. copy api token is not working
4. after copying the share link from the in-progress report once, attempting to copy another document results in 'copied' message, preventing further copying
