feat(settings): move update & telemetry controls into Settings → Behavior (#4592)

Relocate the update and telemetry toggles out of the library settings
menu into the Behavior (Control) panel, where global app settings live:

- New "Update" boxed-list (gated on hasUpdater): Check Updates on Start
  + Nightly Builds.
- New "Privacy" boxed-list: Help improve Readest (telemetry).
- Behavior section order: Update → Security → Privacy.
- Rename "Nightly Builds (Unstable)" → "Nightly Builds" and drop the
  "; may be unstable" note (the channel stays off by default).
- Updater dialog now shows the full version name (e.g.
  0.11.4-2026061506) instead of a parsed date.
- Extract + translate the new strings (Update, Privacy, Nightly Builds,
  Early daily builds) across all 33 locales.
