YAML parsing debug

[kbonney]

Summary

The goal of this PR is to resolve bugs in the yaml_to_blade() function. Currently, there are observed differences in the total weight of blades compared to their design documents.

yaml_to_blade() changes

• Blade length: remove np.ceil and redundant hub-radius arithmetic. Uses exact YAML span value
• Spar cap attributes: use _lp / _hp suffixes to avoid LP overwriting HP (or vice versa)
• Airfoil winding: replace arctan(y/x) gradient check with the shoelace signed-area formula. Avoids divide-by-zero near x = 0
• fabricangle: replace finally: pass with except (KeyError, TypeError): cur_comp.fabricangle = 0
• ValueErrors in _add_components: add missing raise to all four TE/LE reinforcement error sites
• yaml.FullLoader: replace deprecated yaml.Loader
• ispan aliasing: definition.ispan = definition.span.copy() instead of direct assignment
• Import cleanup: remove unused from scipy.stats import mode

BOM changes

Example blade files cleanup

• Removed duplicate files
• Renamed files for clarity on their contents
• Updated tests/example files with new filenames
