Syncing the compilation stage

[TathagataChakraborti]

We want to have a single compilation run to produce the starting point for the Insights tab. This avoids having two separate spreadsheet reads and nightmares with what structures are supported and what is not + no having to map between IDs and slugs from separate reads.

• [ ] Produce starting YAML file for configuring rules @TathagataChakraborti
• [x] Remove slugs and replace them with automated slugs @TathagataChakraborti
• [ ] Modify the encoding script to read from the YAML and compiled JSON instead. @haz
• [x] Remove vestigeal flask stuff from the encoding script @haz
• [ ] Streamline the preference specification process 👀

This is the current compiled JSON schema; and here is an example JSON. Do you need me to modify or add things to it that make your job easier?
