Improvements and fixes

Date filters and the plant Edit page work again, accounts without plants open empty, and the assistant answers how-to questions from the Mirox documentation.

• If you have no plants yet, your dashboard, events, forecasts and exports open empty and no longer show an access error.
• Filtering a list by a date, such as when a ticket was created or is due, no longer fails with an error.
• Choosing "Edit" on a plant in your organization's plant list no longer opens an empty page.
• Your export templates now show their metrics in the row; you can search the list, copy a template's ID, and confirm before deleting one.
• In the export, metrics are listed in the same category order, energy and power first; "Curtailment Losses" and "Technical Loss Energy" replace two earlier entries.
• When you ask the assistant how something works, it now looks the answer up in the Mirox documentation.
• Opening a device's web interface can no longer send your browser to an address outside Mirox.
• Security updates for third-party components.
