Fix: Unpack and store alignment parameters in Resolver

[sashimikun]

Address: #245

This commit modifies langextract/resolver.py to properly unpack and store alignment parameters (e.g., fuzzy_alignment_threshold, enable_fuzzy_alignment) when they are passed to the Resolver constructor via resolver_params (or kwargs).

Previously, these parameters were causing a TypeError in Resolver.__init__ because they were not popped from kwargs and Resolver did not expect them. Additionally, instance-level configuration was not persisted for use in align and resolve methods.

Changes:

• Update Resolver.__init__ to consume alignment parameters from kwargs and store them as instance attributes.
• Update Resolver.align and Resolver.resolve to accept None for these parameters and fallback to instance attributes or default constants.
• Update AbstractResolver signatures to match.
• Add tests/resolver_params_test.py to verify the fix.
