Fix SQLMesh command documentation

Corrected SQLMesh commands to show proper usage:
- Run from project root (not from transform/sqlmesh_materia/)
- Use -p flag to specify project directory
- Use uv run for all commands
- Use esc run for commands requiring secrets (plan, audit, ui)
- Clarified which commands need secrets vs local-only

This aligns with the actual working pattern and Pulumi ESC integration.
