Add date-parameterized sync with production and consumption tables

- Accept ?date= param on POST /eloverblik/sync (defaults to today)
- Populate production table from D06 meter (571313113163368491)
- Populate consumption table from D07 meter (571313113163368507)
- ON CONFLICT DO NOTHING to skip existing data
