fix: emoji selection appends correctly to status input

When focus moves to the emoji picker the input loses focus, making
selectionStart/selectionEnd unreliable. Replace the cursor-tracking
insertion with a simple functional state updater that always appends
the emoji to the end — reliable and appropriate for a short status field.

Also removes the now-unused inputRef and useRef import.
