Latest support for abacus scf output (#875)

Abacus updates its output format, so these keywords were not right. I
have updated them to support both eariler ones and latest one by
removing the unit part.

## Summary by CodeRabbit

* **Bug Fixes**
* Improved robustness when reading ABACUS simulation outputs by
accepting more variations of energy, force, and stress headers.
* More permissive header matching reduces failures from minor log-format
differences.
* Preserves existing convergence and extraction behavior while improving
tolerance for alternate log phrasing.
* Reduces missed or incomplete parses, increasing reliability across
ABACUS log variants.
