v1.46.0

Added

• Encrypted configuration backup and restore: administrators can export the complete HSI
  configuration from Settings → Backup & restore, protected with AES-256-GCM and a
  password-derived key. Restores verify the authenticated encryption, SQLite integrity and schema
  compatibility, retain the previous database as a rollback copy, then restart HSI automatically.
  Files stored in Places and Docker volume contents are deliberately excluded.

Fixed

• Update progress indicators: update, restart and reconnect actions now use HSI's circular
  loading indicator instead of the wedge-shaped inline SVG spinner.
