[Phase49] ChatWindow.Sending.cs 분리 — MessageEdit, StreamingTimers 분할

변경 파일:
- ChatWindow.Sending.cs: 720 → ~300줄 (전송 섹션만 유지)
- ChatWindow.MessageEdit.cs (신규): ApplyMessageEntryAnimation, _isEditing 필드,
  EnterEditMode, SubmitEditAsync (~180줄)
- ChatWindow.StreamingTimers.cs (신규): StopAiIconPulse, CursorTimer_Tick,
  ElapsedTimer_Tick, TypingTimer_Tick (~58줄)
