✨ Enhance log analysis with advanced filtering and search capabilities

Add comprehensive log analysis features to improve troubleshooting workflows:
- Time-based filtering (8pm-6am shifts) with HH:MM format support
- Multi-level log filtering (ERROR, WARNING, EMERGENCY, etc.)
- Full-text search across log content with case-insensitive matching
- Proper line break formatting for readable output
- Line count limiting for large log files

New REST API endpoints:
- /api/logs/errors/{job_id} - Get only error/warning logs
- /api/logs/search/{job_id} - Search logs for specific terms
- Enhanced /api/logs/job/{job_id} with filtering parameters

New MCP tools:
- get_error_logs - Streamlined error analysis
- search_job_logs - Pattern-based log searching
- Enhanced get_job_logs with all filtering options
