fix: resolve stale closure in SpanAnnotationManager keyboard handler

Browse source 
Use selectedSpanIdRef to avoid capturing stale selectedSpanId in the
keyboard event handler closure. Wrap handleDeleteSpan in useCallback
with stable dependencies (reads selectedSpanIdRef.current instead of
the prop directly). Remove selectedSpanId from the useEffect dependency
array since the ref is used instead.
