Refactor: bring order to the scripts loading

**Describe the bug**

We load a lot of tiny scripts. Perf is 100 so it's not a disaster or anything, but it is untidy.

**What is wrong with this content?**

**How could this be fixed?**

concat and min scripts in the footer? Partials should be fairly encapsulated so we are loading them in the partial atm.
I tried writing to a page store but Hugo gave me a gnarly race condition that I could not understand at the time (and I haven't looked since)

This is NBD obviously - the largest script is 4kb.
