feat: disable spellcheck and autocomplete in search input

Add `spellcheck="false"` and `autocomplete="off"` attributes to the 
search input field in the channel list component. This improves 
user experience by preventing the browser from suggesting 
incorrect spellings and previously entered values, ensuring a 
cleaner and more focused search experience.
