Fix O2M ID field handling and enhance import reliability

- Fix critical bug in to_xmlid function: Preserve dots in XML IDs for Odoo format
- Remove '.' from character replacements to maintain module.identifier format
- Fix syntax error in to_xmlid function docstring with proper triple quote escaping
- Enhance batch load debugging with detailed record creation verification
- Add comprehensive error logging for XML ID constraint violations and validation errors
- Improve exception handling to capture failures in fail files instead of aborting
- Add enhanced debugging for load response analysis and record creation counts
- Prevent large base64 data from flooding logs with smart truncation
- Fix ir.model.relation field validation errors with proper error handling
- Gracefully handle Odoo server internal errors during relational imports
This addresses all critical issues preventing successful O2M ID field imports:
1. XML ID constraint violations that were blocking record creation
2. Dot removal in XML IDs that was corrupting module.identifier format
3. Silent failures that were preventing proper error reporting
4. Debugging gaps that made troubleshooting difficult

The enhancement now successfully handles direct database IDs in /id suffixed fields
while maintaining compatibility with existing XML ID functionality.
