A plant's history now imports from its previous monitoring system

The "Import" tab on a plant's "Dataflow" page now takes the ZIP archive exported from the plant's previous monitoring system and matches its devices to components by serial number or name. The import runs day by day and can be paused, stopped, or have what it wrote deleted.

• On a finished import, "Re-import days" writes a range of days again from the same archive.
• Days the plant already recorded itself are never overwritten.
• While it runs, the days written, the readings stored and the time left are shown.
• An interrupted upload resumes when the same archive is picked again.
• A device with no matching component is imported as "Unknown source", or left out.
