Add computed beta fallback and FMP short interest fallback
- compute_beta: 2y weekly returns vs SPY, cov/var formula, capped ±3, BETA_CACHE TTL=3600
- get_fmp_short_interest: calls FMP /v4/short-of-float-symbol when all yfinance short fields are None
- _build_quote_and_stats: accepts sym, uses compute_beta when info["beta"] is None
- PERIODS/YF_PERIOD_MAP: added "2y" support
- test_api: clear BETA_CACHE and SHORT_CACHE in clear_service_caches
