Fix cron auto-import env vars and health check log spam for Firefly III Data Importer

- Source /etc/environment in cronupdate to load addon env vars (FIREFLY_III_URL, etc.)
- Persist cron-needed vars (JSON_CONFIGURATION_DIR, IMPORT_DIR_WHITELIST, etc.) to /etc/environment
- Fix inverted nginx map values that caused health check logs to spam while suppressing real requests
