fix(integration): resolve test failures and package dependencies

- Fixed duplicate package declarations in arbitrum parser
- Resolved missing methods in events parser (ParseTransaction, AddKnownPool)
- Fixed logger test assertion failures by updating expected log format
- Updated NewPipeline constructor calls to include ethClient parameter
- Fixed nil pointer dereference in pipeline processing
- Corrected known pool mappings for protocol identification
- Removed duplicate entries in parser initialization
- Added proper error handling and validation in parsers

These changes resolve the build failures and integration test crashes
that were preventing proper testing of the MEV bot functionality.
