refactor: maintain natural log order in API response and enhance log loading logic

- Updated the API to return logs in their natural order (oldest to newest).
- Modified the loadLogs function in Logs.vue to support incremental updates and maintain scroll position based on user preferences.
- Introduced a hash function to track the last loaded log for efficient updates.
