feat: Add auto-generated maneuver names with edit capability

Added automatic name generation for new maneuvers:
- generate_maneuver_name() creates sensible names (e.g., 'Prograde #1', 'Retrograde @ ν=3.14 #2')
- Names based on burn direction, trigger type, and burn number
- User can still manually edit names if desired
- Validation now allows empty names (for auto-generation)
- Integrates with existing create_maneuver_from_dialog() workflow

Users can create maneuvers faster with auto-generated names, or override with custom names.
