Yijia-Xiao 7c8fe2fe9f fix(data): normalize symbols on the identity and reflection paths
resolve_instrument_identity and the reflection return lookup queried Yahoo with
the raw ticker, so broker/forex/commodity symbols (XAUUSD, BTCUSD, EURUSD)
failed identity or could mismatch the priced instrument even though the price
path already normalized them. Route both through normalize_symbol (#983, #984).

"""Symbol normalization must apply on every yfinance path, not just price fetch.
Regression tests for #983 (instrument identity) and #984 (reflection returns):
a broker symbol like XAUUSD must resolve to the same Yahoo symbol (GC=F) that
the price path uses, so identity and realized-return lookups hit the right
instrument instead of failing/mismatching.
