* Fix ParameterExpression.sympify() for RPOW operations

Fixes #15583

The sympify() method was not correctly handling reverse power
operations (RPOW). When converting ParameterExpression to sympy,
RPOW operations need to swap operands (rhs ** lhs instead of
lhs ** rhs) to match the Rust implementation.

This fix adds special handling for RPOW, RDIV, and RSUB operations
to correctly swap operands before applying the operation.

* Add test and release note for RPOW sympify fix

- Add test_sympify_rpow_operand_order() to verify the fix for issue #15583
- Add release note documenting the bug fix

This addresses reviewer feedback to add tests and release notes.

* Add comprehensive tests for all reverse operations (RPOW, RDIV, RSUB)

This improves test coverage for the sympify fix by testing all three
reverse operation types that were added in the fix. This addresses
the Coveralls coverage report showing only 25% coverage.

* Fix POW operation to use RPOW when LHS is Parameter and RHS is expression

Fixes #15583

When a Parameter is the LHS and an expression (ParameterExpression) is the RHS
of a POW operation, we should use RPOW instead of POW. This ensures the repla... (continued)
