[MOV] finance: move fiscal localisation pages and merge /overview/

The content written in the fiscal localisation pages are not only for
Accounting, but also for other apps such as Payroll and Point of Sales.
This commit moves the content to the "Finance" level, to better reflect
this reality, and merges the pages in the /overview/ folder in the main
category page.
