InDesign API doc pages for Preflight-related objects accidentally placed in ParagraphDestination folder

Commit 9bfba07c2b838 seems to have moved e.g. PreflightProcess to the path /src/pages/omv/p/ParagraphDestinations/PreflightProcess/index.md which makes navigation from the web page sidebar result in a 404.

For the web visitor that means that the expected URL https://developer.adobe.com/indesign/uxp/omv/p/PreflightProcess/ won't work while https://developer.adobe.com/indesign/uxp/omv/p/ParagraphDestinations/PreflightProcess/ surprisingly does (if entered manually).

Start by inspecting /src/pages/omv/p/ParagraphDestinations/PreflightProcess/index.md and the related sidebar navigation. Identify all Preflight-related pages placed under ParagraphDestinations, restore their expected /src/pages/omv/p// locations, and verify that the documented URLs no longer produce 404s.
