Update server reports extension version, fix its build breaks, and reduce its size to 86Kb (#4062)

* Updated version
* On building found it had build break due to unused imports. Turns out none of the code is used (it's just a package.json + SQL file extension) so removed it all
* Removed all unnecessary node module imports, reducing size from 5.4MB to 86KB. We should probably do this for all extensions
