refactor: extract Settings screens into SettingsViews.swift (v5 step 4, 6/n)

Pivots the god-file decomposition to ContentView.swift (the other ~3.9k-line
file). Unlike DomainViewModel, this is a set of independent SwiftUI View structs,
so it splits with no shared-state entanglement.

- Moves the Settings surface into SettingsViews.swift: SettingsView (the tab
  root, presented from RootTabView) plus its nine file-private section screens
  (Display, History & Network, iCloud Sync, Local API, Monitoring, Import &
  Export, Data Management, About) and the DataImportPreviewSheet. Pure move.
- The private section screens stay file-private together in the new file, reached
  only through SettingsView's navigation links. Zero visibility changes were
  needed: the block references nothing file-private to ContentView.swift, so the
  ContentView diff is pure deletion.

ContentView.swift: 3881 -> 2739 lines. App builds clean; unit suite 58/58.
No project.pbxproj change (DomainDig/ is a synchronized group).
