💄 Misc cleanup in middleware, helpers & apps (#7479)

no issue

- unsued code:
  - there are no public assets anymore, might need to use this instead of shared in future, but for now lets remove it to reduce confusion
  - the `input password` box was incorrectly registered as an admin helper, thinking that was needed in order to render the default template. This isn't needed.
- apps:
  - small structure & comment update to amp app
  - moving input_password helper into private blogging app
  - refactor helpers in subscribers app
