fix(docs): correct broken internal links to match actual routes

Fix links verified against routes.ts:
- /settings → /settings/system
- /settings/updates → /settings/update (singular)
- /settings/maps-manager → /settings/maps
- /settings/wikipedia-selector → /settings/zim
- /settings/zim-manager → /settings/zim
Replace Wikipedia Selector references with Content Manager to
match sidebar labels in SettingsLayout.tsx.
