Closes #22059: Consolidate numeric GraphQL lookup classes via shared mixin
Extract _NumericLookupMixin with shared get_filter() and filter() methods. IntegerLookup, BigIntegerLookup, and FloatLookup each inherit from it and declare only their type-specific fields, eliminating triplicated logic. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
