refactor(IPC): adapt to the 0.15.0 daemon wire protocol progress events

[rikettsie]

With ringdrop 0.15.0 the new IPC daemon protocol added granular information about progress of files belonging to a directory blob: kind, size and the included file names. We should adapt the GUI to this IPC changes.

• Bump ringdrop dependency to 0.15.0;
• Add FileProgress to receive IPC progress notifications from daemon;
• Extend BlobRow with new fields (kind, size);
• Update typescript BlobRow type with kind/file_count/size_bytes;
• Fix ReceivePanel: channel ID, correct event name (FileProgress);
• Add per-file progress display to RemotePanel
• Show kind and size in BlobTable
