Refactor moderation actions to include channel and source metadata

- Updated moderation action functions to include `channelId` and `source` in the metadata for better tracking of actions.
- Introduced an `auditFrom` function to streamline the addition of audit information across various commands.
- Removed `prisma/migrations` from .gitignore to ensure migration files are tracked.
- Enhanced the `CreateCaseInput` type to accommodate new metadata structure.
