fix: add KR_FALLBACK_STOCKS for domestic scanner when ranking API returns empty (#153)

KIS VTS (paper trading) does not return data from the domestic
volume-rank API. The smart scanner had no fallback for KR market,
causing permanent "No candidates" and zero trades all day.

- src/config.py: add KR_FALLBACK_STOCKS with 10 major KRX stocks
  (삼성전자, SK하이닉스, NAVER, 현대차, 셀트리온, LG화학, 카카오,
   삼성SDI, 삼성바이오로직스, 기아)
- src/main.py: pass KR fallback stocks to scanner.scan() for domestic
  markets (mirrors the overseas build_overseas_symbol_universe pattern)
- tests/test_main.py: add TestKrFallbackStocksConfig (3 tests)

Closes #153
