android, desktop: trim settings reorg diff

- Remove 5 dead strings from base/strings.xml (privacy_and_security,
  database_passphrase_and_export, settings_section_title_chat_database,
  settings_section_title_support, settings_section_title_app) — no
  Kotlin references after the reorg.
- Drop the now single-variant CurrentPage enum in
  NotificationsSettingsView; replace with a direct callback.
- Read userDisplayName locally in HelpAndSupportView instead of
  threading it through SettingsLayout/SettingsView/Preview.
