docs: move FeeComponents operator== Doxygen comment

[mohityadav8]

Description:

Move the orphaned Doxygen comment for FeeComponents::operator== to the public declaration in FeeComponents.h.

• Relocate the existing operator== Doxygen block above the public declaration
• Remove the orphaned documentation block from the bottom of the class
• Align equality operator documentation placement with project conventions
• Preserve existing behavior (documentation-only change)

Related issue(s):

Fixes #1613

Notes for reviewer:

This is a documentation-only change. The existing Doxygen comment was moved from the bottom of the class to immediately above the public operator== declaration. No code or behavior changes were made.

Checklist

• Documented (Code comments, README, etc.)
• Tested (unit, integration, etc.)
