docs: fix route_to and bypass documentation in advanced solve guide

- Correct route_to syntax to use strategy names (ipopt, madnlp, exa) instead of family names (solver, modeler, discretizer)
- Fix ambiguous options explanation - only occurs when strategies from different families share option names within same method
- Update bypass section with real Ipopt example using mumps_print_level
- Add note about force alias for bypass
- Remove redundant section about combining route_to and bypass
- Expand describe output description
- Fix markdown formatting issues
