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

[oleksii-tumanov]

Summary

• collect method-scoped Kotlin receiver types from class properties, parameters, getter returns, and local constructor/getter bindings
• resolve member calls only when the receiver type and selected method owner are unambiguous, with package/import, inheritance, extension, companion, and lexical-scope guards
• preserve existing Kotlin dispatch for super, object/companion-qualified calls, private visibility, and inner-class dispatch receivers

Fixes #1699
