Fix Mealie madplan: REST response for stor (16KB+) til HA attributes

- Nyt Python-script henter fra Mealie API og gemmer forenklet JSON (754 bytes)
  til /config/www/mealie.json (kun dato, navn, slug per opskrift)
- REST sensor peger nu på lokal fil via http://localhost:8123/local/mealie.json
- shell_command + automation opdaterer filen hvert 30. minut og ved opstart
- Løser 'Ingen planlagt' og 'buttoncardtemplateerror' i dashboard
