Root cause: ArcoDesign Tree loadMore callback receives NodeInstance where
the key is at node.props.dataRef.key, not node.props.key. The old code
passed node.props directly which resulted in undefined key, causing
child directory loading to silently fail.
Fix:
- Access node key via node.props.dataRef?.key ?? node.props._key
- Add showLine + blockNode + folder icons for better visual hierarchy
- Add path display with copy button in selection modal
- Add unmountOnExit to reset state on close
Closes#19
Three community-requested features:
1. CLI password reset: `backupx reset-password --username admin --password xxx`
Docker users can run via `docker exec`. No full app init needed.
2. Audit logging: async fire-and-forget audit trail for all key operations
(login, CRUD on tasks/targets/records, settings changes).
New UI page at /audit with category filter and pagination.
3. Multi-source path backup: file backup tasks now support multiple source
directories packed into a single tar archive. Backward compatible with
existing single sourcePath field.
