[MOV] pos: content to top-level TOC page + improve structure

This commit is part of a larger work to improve the documentation's
structure. The toctree structure used to add levels to create categories
and make the structure visually more understandable.
With the new version of the documentation, plenty of these categories
are now redundant.

This commit improves the structure of the "Point of Sale" app:

- it removes a useless "overview" category and moves its two docs to the
  top-level TOC page
- it adds a brief explanation at the "app" level, including links to
  relevant docs
