feat: streamline dashboard UI and improve refill reminder (#86)

- Hide Reorder Reminder card when reminders are enabled (avoids redundancy with Reminder Bar)
- Show all low stock medications in Reminder Bar instead of just the next one
- Rename 'Reorder' to 'Refill' throughout the app
- Make medication names clickable in Refill Reminder card (opens detail modal)
- Add daysLeft display for each low stock medication
- Update translations (EN + DE)
