Fix database queries for usage in HTML report

[andigandhi]

The "paths" and "secrets" tabs of the HTML export currently throw the following error:

This is due to the query definition in line 65 in the file common.js. There the "${select}" part already contains a "ORDER BY" instruction which is followed by a "WHERE". This leads to a [Grid.js] [ERROR]: Error: near "WHERE": syntax error error when trying to execute the query in the browser.

I've encapsulated the SELECT parts of the queries in another SELECT * FROM ( instruction. This ensures the function in other parts of the code (e.g. in reporting.py) while still being able to append a WHERE clause.

Thank you for this awesome tool!
