fix: exclude account_id and virtual fields from archive_content DB writes

- Adds fields_to_exclude_from_db to Archive_Content_Base to prevent SQL errors on non-existent columns.
- Updates documentation for V3 Create/Update patterns and the x-ae-ignore-extra-fields header.
- Propagates account_id_random to hosted file and media processing methods.
