fix(extract): resolve Java member calls by receiver type

[oleksii-tumanov]

Summary

• preserve the receiver and static receiver type for Java member calls
• resolve explicit type receivers, current-class fields, parameters, and typed locals with method-scoped bindings; skip ambiguous, inherited, and chained receivers

Fixes #1696

Result

run -> PaymentGateway.ping [EXTRACTED]
run -> PaymentGateway.charge [INFERRED]

The three charge() calls deduplicate to one edge, and no edge targets the same-named AuditLog methods.
