fix(analytics): harden analytics opt-out and feedback surfaces (#423)

Server stops phoning Sentry home after opt-out (release-health sessions + client reports off); settings saves diff-send only changed keys so a stale tab cannot revert an instance-wide opt-out; disabling analytics hides the feedback UI immediately; optIn resumes PostHog after re-enable; onboarding survey writes time out at 15s; inline tool-feedback prompt arms a shown-cooldown.
