fix(ui): upload chunk size, cached file display, chat names, file delete, inline thumbnails

- Upload chunks capped at 64KB to avoid WebRTC DataChannel max-message-size
- Show cached files immediately while WebRTC connects (tabs visible during connection)
- Persist sender_name in chat store (SQLite) — no more UUID display in history
- File delete action in menu (node admin only, enforced server-side)
- FILE_DELETE / FILE_DELETE_ACK MNP message types
- Inline image thumbnails in chat attachments (download+decrypt, Signal-style)
- Member panel: "Owner" label instead of "Group admin" to avoid hub/group admin confusion
- Create group page: hint about needing a node
- Refresh index after chat file attachment upload
