2.4.0

New features

• Device triggers and a refresh button — build no-code automations that fire when a parcel is registered, changes status, or gets a new expected delivery time, and add a button to poll DHL on demand.
• Deliveries calendar — a per-account calendar entity showing your incoming parcels on their expected delivery day, ready to overlay on your own calendar.
• Diagnostic "Last successful update" sensor — alert on a silently stale integration.

Improvements

• A DHL outage no longer pushes you into re-authentication — server errors and genuine auth failures are now told apart.
• Re-authentication is guarded against accidentally binding the entry to a different DHL account.
• Diagnostics now redact person and shop names.
• Refresh-interval options are translated, and shared wording is aligned with the other carriers.
