feat(settings): split overloaded Library tab into a new Organization tab

Move download path templates, priority tags, and auto-organize
exclusions out of the Library settings section into a dedicated
Organization section, so Library keeps location-focused settings
(roots, extra paths, example images, metadata) and Organization holds
file-arrangement rules. Translated settings.nav.organization for all
locales.
