[FEATURE]: Enhance Text_Input with Interactive File Upload UI and Error Boundaries

### Feature and its Use Cases

Currently, the Text_Input component lacks adequate visual feedback during file uploads (PDF/MP3). After clicking "Browse File" and selecting a document, the user interface does not reflect the selection, which creates a confusing user experience.

Current UX Gaps (Before):
The user cannot see the name of the file they just selected.
There is no way to cancel or clear a mistakenly selected file.
There are no visual indicators for upload progress or transfer speed, leaving the user guessing if the application is processing or stalled.
There are no error boundaries to visually warn the user if an upload fails.

Proposed Solution
I have designed and developed a comprehensive, interactive upload UI from scratch to resolve these pain points and elevate the user experience.

Key Features Implemented:
File Visibility & Management: The UI immediately renders the selected file name (e.g., sample.pdf) alongside a functional '✕' button, allowing users to easily clear their selection.
Real-Time Progress: Integrates a smooth, gradient-styled progress bar that tracks the exact percentage of the upload lifecycle.
Dynamic Speed Tracking: Calculates and displays a simulated network transfer speed (e.g., KB/s).
Robust Error Handling: Features a dedicated error state that catches failed uploads and displays a clear red warning message, preventing infinite loading loops.
The Solution in Action (After):

Next Steps
I have already built this feature locally. I will be opening a Pull Request immediately following this issue to propose the code changes for review.
