Refactor HttpRequestCustomRecipe getVisitor() method for improved readability and maintainability

[Copilot]

Overview

The HttpRequestCustomRecipe.getVisitor() method contained extensive logic that was difficult to follow due to repetitive code patterns and lack of documentation. This PR refactors the method to improve readability and maintainability while preserving the exact same logical execution and performance characteristics.

Changes Made

1. Added Helper Methods

• findBaseVariableIdentifier(): Extracts common logic for traversing method invocation chains to find the root variable identifier
• applyFormatting(): Centralizes the application of formatting transformations

2. Enhanced Documentation

• Added comprehensive JavaDoc comments for both visitNewClass and visitMethodInvocation methods
• Added clear section headers to group related transformations (body methods, URL methods, header methods, utility methods)
• Documented the purpose and behavior of each transformation group with inline comments

3. Improved Code Organization

• Grouped method transformations by logical categories:
  • Body methods: setBody(String), setBody(byte[]), getBodyAsBinaryData()
  • URL methods: setUrl(URL), getUrl()
  • Header methods: setHeader(..)
  • Utility methods: copy()
• Added clear section delimiters with === comments for better visual separation
• Maintained the exact same logical flow and execution pattern

4. Reduced Code Repetition

• Eliminated duplicate variable identifier traversal logic by using the helper method
• Centralized formatting application calls
• Preserved all existing functionality while improving maintainability

Before and After

Before: The method contained ~90 lines of dense, repetitive code with multiple instances of the same patterns for method matching, template building, and variable identifier finding.

After: The method is organized into logical sections with helper methods, comprehensive documentation, and clear separation of concerns, making it significantly easier to understand and maintain.

Validation

• ✅ Code compiles successfully with no errors
• ✅ Maintains identical logical execution flow
• ✅ Preserves all existing transformation behaviors
• ✅ No performance impact - same operations, better organized

Fixes #45605.
