feat(birdnet-go): add LOG_MAX_SIZE_MB and LOG_MAX_AGE_DAYS options to manage log storage

Add addon options to control birdnet-go log file rotation:
- LOG_MAX_SIZE_MB (default: 50): maximum size per log file before rotation
- LOG_MAX_AGE_DAYS (default: 7): maximum days to retain old log files

On startup, the addon:
1. Configures birdnet-go's logging.file_output settings in config.yaml
2. Sets max_rotated_files to 3 and enables compression
3. Trims existing log files exceeding the configured age

Fixes #1922
