smill f361fee969 feat: named case-result load combinations with full GUI support
Snapshots the current development tree, headlined by proper load
combinations (user request): a reusable LoadCombination entity of
weighted completed static-case results (e.g. 1.2xDead + 1.6xLive).

- core: LoadCombination/LoadCombinationItem entities, Project
  integration (lookup, unique ids, reference validation)
- services: combinations.py (linear superposition + envelope),
  exported via services __init__
- commands: undoable Add/Delete/Update for combinations
- GUI: Load Combinations manager dialog, Run-dialog evaluation,
  envelope display in Results panel, Combinations tab in Table dock
- tests: unit coverage (validation, math, error paths) + integration
  superposition check vs a single factored run

"""Shared pytest configuration.
The GUI suite is headless by default: unless the caller already chose a
platform, ``QT_QPA_PLATFORM=offscreen`` is set here, before pytest-qt
builds its session ``QApplication``. An explicit caller value is respected.
OpenseesPy is a process-global singleton, so a lazy autouse guard wipes the
domain after every test. The import is inside the teardown so that
``tests/unit`` never imports the solver.
