Move to a safe query structure for all the queries at contractwork.vipulnaik.com

[vipulnaik]

Currently, the query structure uses string interpolation to fill in values of worker, topic, payment, etc. In theory, this could allow for some kind of SQL injection into the query that could cause inappropriate SQL code to be run. I would like to move to a safer query structure that uses prepared statements. We've already been using this safer query structure in a few places, so it should be easy to do. It just needs to be applied across a bunch of files.

My work is here: https://github.com/riceissa/contractwork/tree/safe-query

I think I found all the unsafe queries. All pages seem to work so this should be ready to be merged. I couldn't test the tables related to impact because those query from Wikipedia Views, which I don't have on my local machine. e.g. you might want to check https://contractwork.vipulnaik.com/format.php?format=Timeline#formatImpact

I don't have push access to this repo, so that's why it's in my own fork. Let me know if I need to send a pull request.
