Improve logging documentation

[Daniele Procida]

The Django logging topic contains a lot of valuable information, but its structure can be greatly improved. I plan to refactor it across three documents:

• a how-to guide for practical usage
• a reference guide containing technical description
• the existing topic that explains logging

This is in accordance with ​Django's own documentation structure, and the principles outlined in the ​Diátaxis framework.

As agreed with the Django fellows, pull requests for this will be small and frequent, and the work will proceed iteratively rather than delivering a finished tranche of work in one piece.

Refs #32880 -- Rearranged logging security notes.

Expanded security notes and moved them under a new explanation heading
of their own for future reference and expansion.

Removed specific reference to Sentry since there are multiple
third-party services that fulfill that role.

Refs #32880 -- Renamed/reordered logging topic sections.

Moved sections so that how-to type material is all together, and
renamed headings so it's clearer what those sections are about, in
anticipation of creating a separate how-to document and expanding
the material.

Refs #32880 -- Made some titles consistent in how-to documents.

This retitles documents for consistency, since some already (correctly)
begin "How to...".

Daniele, is there anything left for this ticket? or can we close it as fixed. I think it's ready.
