fix: use TEST-prefixed IDs in integration tests to avoid real-data conflicts

Integration tests used ISSUER::0000320193 (Apple's real CIK) and
SYM::AAPL::XNYS as hardcoded IDs. After the real pipeline inserts
actual AAPL data, subsequent test runs fail with UniqueViolationError
since the db_session rollback only undoes intra-test writes.

Changed to ISSUER::TEST::0000320193 and SYM::AAPL::XNYS (distinct
from the real SYM::AAPL::US) while keeping ticker="AAPL" so the
Oracle price service returns real price data for label/feature tests.
