Hannah Wolfe 4237446277 Misc cleanup & consistency amends (#9002)
no issue

- Consistent naming for postLookup
   - makes it easier to search and inspect the various usages
- Cleanup unneeded code
- Make res.render calls more consistent
- add some consistency to the calls to res.render
- Remove ancient reference to dataProvider
- Let's call it models everywhere now...
- Use consistent formatting across the API
- we're no longer using alignment in vars
- Misc other consistency changes in API
- always refer to local utils as apiUtils
- logical grouping of requires - dependencies, utils, "lib common" etc
- use xAPI to refer to API endpoints, e.g. mailAPI, settingsAPI for clarity
