test(RefreshButton): type-compiler checks (#2602)

[soumyasekharshee265-ux]

Description

Fixes #2602

Added a new isolated test file components/dashboard/RefreshButton.type-compiler.test.tsx covering TypeScript Compiler Validation & Schema Constraints Stability (Variation 10) for the RefreshButton component.

What's covered (5 test cases):

• Validates baseline RefreshButtonProps property fields (username) align perfectly with the public contract via expectTypeOf
• Ensures invalid structural definitions (wrong types, wrong key names, nullable variants) are caught and blocked during static assignment checks
• Verifies the RefreshButton props envelope seamlessly tolerates minimal and extended consumer shapes without dropping compilation support
• Asserts that an associated strict zod validation schema rejects out-of-bounds username fields with explicit flat error reports
• Proves that standard compliant RefreshButtonProps records cleanly clear validation gates and preserve underlying type integrity definitions

Test results:
✓ Test Files 1 passed (1)
✓ Tests 5 passed (5)
