fix: Update full_chain_odd_LRT.py to follow full_chain_odd.py (#3977)

In this PR full_chain_odd_LRT.py is updated according to full_chain_odd.py.

<!-- This is an auto-generated comment: release notes by coderabbit.ai -->
## Summary by CodeRabbit

- **New Features**
  - Introduced a command-line argument `--output-obj` to toggle object output.
  
- **Enhancements**
  - Updated ambiguity resolution configuration to use mathematical constants for `phiMax` and `phiMin`.
  - Added new parameters for seeding and track selection to improve configurability and precision.
  - Changed the vertex fitting method to a more advanced algorithm.

These updates enhance the script's functionality and improve the particle tracking and reconstruction processes.
