Make the Generator's server-name lists editable, add themes, import names from Skatteverket

Name lists now live in settings instead of the web bundle. Admins edit them under
Settings -> Names (add/remove names, create/rename/delete lists, reset a built-in
list). Names are folded to hostname-safe form (a-z, 0-9, hyphen) and validated on
the server; saves are audited.

Adds Swedish boy names, Pixar, Norse mythology and Astrid Lindgren lists, and
lengthens the Swedish girl and Disney lists. "Mixed" is now every list with each
name counted once.

Admins can preview and import the most common Swedish names from Skatteverket's
open "Namn pa nyfodda" data (girls or boys, latest 1-5 full years); nothing is
stored until the editor is saved. The old comment that credited SCB statistics is
gone: SCB stopped publishing name statistics after 2023.

Privacy page, README and ROLES updated for the new outbound call and page.
