Refactor MARS-1409: Rollback changes to A_SOURCE_FILE_RECEIVED and related tables

Browse Source 
- Dropped A_WORKFLOW_HISTORY_KEY column from A_SOURCE_FILE_RECEIVED with data preservation.
- Removed unnecessary checks for column existence during rollback.
- Updated A_SOURCE_FILE_CONFIG, A_TABLE_STAT, and A_TABLE_STAT_HIST to their pre-MARS-1409 structures, excluding new columns added in MARS-1409.
- Adjusted FILE_ARCHIVER package to reflect changes in statistics handling and archival triggers.
- Revised rollback script to ensure proper order of operations for restoring previous versions of packages and tables.
