A missing .env file no longer causes a fatal error. Env vars can now
come from the container environment (Docker/systemd) or a .env file
interchangeably.

- Route all log output to AWP_LOG_FILE (from .env) if set, else stderr
- Log errors explicitly before returning so they appear in the log file
- Replace log.Fatal in fetch.go with proper error return so callers control logging
- Remove chatty success/no-op log lines that would bloat cron log files
