Migrate SimulationParams models to flow360-schema

[benflexcompute]

Summary

• relay SimulationParams -> leaf models imports from the Python client to flow360-schema
• keep client module paths stable while moving the schema source of truth out of the client repo
• include the small client-side follow-up fixes needed after the migration, including translator validation scope and relay/lint cleanup

Notes

• schema-side implementation landed in flexcompute/flex#11061 and is now merged
• this PR keeps the client surface mostly as 1:1 relay modules to minimize review noise

Validation

• poetry run pylint $(git ls-files "flow360/*.py") --rcfile .pylintrc
• export PYTEST_CACHE_DIR="./tests/.pytest_cache" && poetry run pytest -c tests/pytest.ini -rA tests/simulation
• targeted schema/client migration regression tests run during implementation

Note

Medium Risk
Medium risk because many simulation/meshing/material model definitions and validators are replaced with schema re-exports, so any schema/client version mismatch or subtle import/validation differences could break user code at runtime.

Overview
Migrates the Python client’s simulation model source-of-truth to flow360-schema by replacing local implementations of boundary split helpers, meshing parameter models (edge/face/volume/snappy/specs/params), and material models with thin relay modules that re-export the schema types under the existing client import paths.

Updates validation wiring to match the new ownership (e.g., meshing_validators now lazily resolves validate_snappy_uniform_refinement_entities from the schema), while keeping the public API surface largely stable for downstream imports.
