[image_uploader] Fix Clear Filters functionality in Imaging Uploader

[arnav-makkar]

Brief summary of changes

• Fixed Child Component Processing: Updated FilterForm.js to correctly process child components that rely on defaultProps for their onUserInput callback.
• Improved Reset Button Handling: The logic for identifying the "Reset" button has been simplified and hardened. It now explicitly targets any ButtonElement with type='reset' to ensure the clearFilter handler is attached, regardless of whether a custom callback was passed from the parent. This resolves issues where passing a bound function would prevent the clear logic from activating.
• Added fallback logic for identifying component names (displayName vs name) to prevent potential errors with different component definitions.

Verification

Verified that clicking "Clear Filters" now clears all filter fields (text inputs and dropdowns) and removes query parameters from the URL.
