Elixir Alerts

This update delivers a broad round of reliability fixes and performance tuning across Elixir Alerts to make medication reminders feel instant, accurate, and stress-free. We improved reminder scheduling in tricky cases (time-zone changes, Daylight Saving Time, and overnight doses), reduced duplicate/missed notifications, and tightened snooze behavior so rescheduled alerts fire exactly when expected. SMS delivery is more resilient with smarter retry logic, clearer delivery statuses, and faster hand-off to ClickSend; in-app alerts now appear consistently even after long periods in the background. The app launches quicker, uses less battery during continuous use, and stays responsive while syncing large histories or restoring backups. We corrected intermittent badge count mismatches, fixed rare crashes during reminder edits, and hardened background scheduling on newer devices. Charts and history views load faster with lighter memory use, and we cleaned up edge-case rounding in daily/weekly adherence stats. Accessibility is improved with more readable text, better VoiceOver labels, and higher-contrast buttons in dark mode. Finally, we polished animations, refined haptic feedback, and squashed dozens of minor UI glitches for a smoother, more dependable experience.
