ADFA-5337 chore(ui): hide the analytics opt-in UI when analytics is compiled out

Follow-up to the conditional Firebase build: when built without google-services.json
(BuildConfig.ANALYTICS_ENABLED = false) there is nothing to share, so the opt-in UI
should not appear.

- SettingsSubFragment: the "Share usage statistics" toggle is not added.
- AboutFragment (+ fragment_about.xml): the "Share anonymous data" row + description
  are GONE (ids added to hide them).
- WizardActivity / SetupSectionFragment: the first-run analytics enrollment prompt is
  skipped and the flow proceeds.

No change when analytics is enabled (file present): the UI shows exactly as before.
