Pasukhin Dmitry ae7e259e17 Foundation Classes - align modern Math* APIs with legacy math_* behavior (#1134) ...

MathLin:
- Return full matrix solutions for multi-RHS APIs.
- Add LinearMultipleResult for matrix RHS solve results.

MathSys:
- Fix Newton2D/3D/4D tiny-step exit logic: re-check residual at updated point and return OK when converged.

MathUtils / MathInteg:
- Add modern Gauss points/weights implementation in MathUtils_Gauss.cxx.
- Keep legacy-table parity for orders 1..61 and compute fallback for higher orders.
- Make GaussAdaptive use IntegConfig InitialOrder/MaxOrder with bounds validation.
- Propagate ordered Gauss points/weights retrieval failures in set/multiple integration.
- Extend BracketMinimum API with bounded/options-based behavior.

Tests:
- Extend MathLin, MathSys and MathInteg tests for new behavior and regressions.
- Add MathUtils bracketing tests.
- Add MathLin_EigenSearch parity test coverage against legacy solver.

Documentation:
- Update MathLin/MathInteg/MathUtils READMEs to match current APIs and behavior.
