… scraped

Fixed two critical issues preventing Loki from receiving logs in production:

1. Logback Configuration:

   • Split logger configurations by Spring profile
   • Dev profiles: write to CONSOLE only
   • Prod profile: write to both JSON (stdout) AND ASYNC_FILE
   • Previous bug: loggers had additivity=false with only CONSOLE ref, ignoring ASYNC_FILE even in prod mode

2. Docker Compose:

   • Added logs volume mount to abada-engine service in release compose
   • Logs are now accessible to Promtail on host filesystem

Additionally:

• Created alternative promtail-config-docker.yaml for Docker logging driver
• Added comprehensive troubleshooting documentation

Verified:

• Logs written to file (27 lines)
• Promtail successfully scraping
• Loki receiving logs with proper labels (filename, job, service_name)
• Query {service_name="abada-engine"} returns log entries
