fix: improve date formatting and backup path handling

- Updated `formatTimeAgo` in `AdvancedSettingsPageClient` to use a fixed format for hydration consistency.
- Refined `formatDate` in `BackupSettingsPageClient` for consistent server/client formatting.
- Refactored `BackupService` to use `getCurrentBackupPath` for all backup path references, ensuring up-to-date paths and avoiding caching issues.
- Added `getCurrentBackupPath` method to dynamically retrieve the current backup path based on environment variables.
