Separate loading states to distinguish between different operations:
- activeCommentDetailLoading: loading comment details, delete/resolve operations
- replySubmitting: sending new replies
- replyUpdating: editing existing replies
Changes:
- Add replySubmitting and replyUpdating states to comment store
- Restore full-screen loading overlay for comment detail loading
- Use inline spinner (RiLoader2Line) in send/save buttons for reply operations
- Update loading state usage in handleCommentReply and handleCommentReplyUpdate
- Pass separated loading states from workflow index to CommentThread component
Benefits:
- UI clarity: different loading states have appropriate visual feedback
- Better UX: users can still navigate while sending replies
- Clear separation of concerns: each operation has its own loading state
