Relax all cardinality restrictions in UBERON ontology

- Removed 60 cardinality restrictions from intersection_of and relationship statements
- Types removed: exact cardinality (49), min cardinality (7), min_cardinality underscore variant (2), exactly constraints (2)
- Affects anatomical connections, organ membership, structural composition, and spatial adjacency relationships
- Added systematic script src/scripts/relax-cardinality-restrictions.pl for future use
- Reasoners will now process these axioms instead of ignoring them due to cardinality constraints
