- libs/oracle_client/alpaca.py: Added get_multi_daily_bars() and
get_multi_intraday_bars() helpers that call Oracle's /api/v1/price/data
and /api/v1/alpaca/intraday endpoints respectively. Oracle handles
symbol normalization (e.g. BF-B → BF.B) internally, so symbols like
BF-B no longer crash the screening chunk.
- apps/paper_trader/alpaca_broker.py: get_bars() and get_intraday_bars()
now use the new Oracle client helpers instead of the Alpaca SDK
StockBarsRequest, eliminating direct Alpaca bar API calls from broker.
- apps/orb_trader/engine.py: Removed per-symbol BF-B workaround (now
unnecessary since Oracle normalizes the symbol server-side); kept outer
try/except for chunk-level resilience.
