Fix crypto profile notification i18n

[Pigbibi]

Summary

• localize both crypto_live_pool_rotation and legacy crypto_leader_rotation strategy names in notifications
• update crypto-strategies dependency pin to v0.4.8
• add coverage for legacy profile localization and settings resolution

Validation

• python -m ruff check notify_i18n_support.py tests/test_notify_i18n.py tests/test_runtime_config_support.py
• PYTHONPATH=.:../QuantPlatformKit/src:../CryptoStrategies/src python -m unittest tests.test_runtime_config_support
• PYTHONPATH=.:../QuantPlatformKit/src:../CryptoStrategies/src python - <<'PY' ... legacy/new notify localization assertions ... PY

Note

• tests.test_notify_i18n was not runnable on this VPS because the local environment is missing numpy; the failure occurs while importing quant_platform_kit.binance.market_data before test execution.
