Refactor transcript fetching and processing scripts

- Introduced a new function `fetchTranscriptContent` to handle fetching transcripts with optional authentication.
- Enhanced error handling and logging for transcript fetching.
- Updated the `parseTranscriptToMessages` function to improve message parsing logic.
- Replaced the old session processing logic with a new approach that utilizes `SessionImport` records.
- Removed obsolete scripts related to manual triggers and whitespace fixing.
- Updated the server initialization to remove direct server handling, transitioning to a more modular approach.
- Improved overall code structure and readability across various scripts.
