Materialize HK market history inputs

[Pigbibi]

Summary

• keep US market_history strategies on the existing loader-function contract
• materialize HK direct market_history profiles into per-symbol date/close histories before strategy evaluation
• add focused adapter coverage for HK materialization while preserving the US loader path

Verification

• /usr/bin/python3 -m py_compile application/runtime_strategy_adapters.py tests/test_runtime_strategy_adapters.py
• git diff --check

Full pytest was not run on the VPS because the available Python environments do not have pytest/pandas installed, and installing pandas on this 2GB VPS is intentionally avoided.
