Fix/mobile input realtime

[Rozerxshashank]

Addressed Issues:

Fixes #96

Additional Notes:

Real-time Typing: Removed the "composition guard" that was causing mobile browsers to wait for a space or word completion
before sending letters. Characters are now delivered to the server immediately as you type.

Backspace Fix: Added e.preventDefault() and explicit input clearing to the backspace handler. This stops the browser from trying to "fix" words after a deletion, which was causing the server to be flooded with previous text fragments.

Input Hardening: Added spellCheck={false} and inputMode="text" to the hidden input field. This tells browsers to disable aggressive predictive text and autocorrect engines that often interfere with remote control functionality.
