build(deps): update cvxpy version from 1.5.3 to 1.6.5 in requirements (#1203)

* build(deps): update cvxpy version from 1.5.3 to 1.6.5 in requirements

* Add ECOS solver and improve solver handling for stability

Added ECOS to requirements and enhanced compatibility with cvxpy solvers by specifying 'order' for matrix reshaping. Updated solver configurations in rocket landing and pendulum control for consistency and reliability. Improved test behavior by enforcing stricter warning handling in pytest.
