Add OARMP routing engine, dashboard and documentation

- Complete routing engine: ingest, optimizer (CG+B&B), maintenance
  monitor, metrics, pipeline, quality checks
- Streamlit dashboard with Input/Output tab structure, editable data
  editors, interactive Folium map with satellite layer and maintenance
  base highlights, FH stacked bar chart with TTM availability
- CSV data files: AERONAVES, CHECKS, AIRPORTS, ESCALA DE VOO
- README, CONTEXTO and CHANGELOG added
- Remove legacy pre_process scripts and raw binary files (PDFs/xlsx)
- Update .gitignore to exclude outputs/, data/, raw/*.pdf, raw/*.xlsx
