Codebase improvements: caching decorator, Pydantic v2, DB indexes, connection pooling, Alembic

- Add @with_cache() decorator to eliminate ~15-line caching boilerplate per endpoint
- Apply decorator to 8 existing endpoints (stocks, alpaca, finra) and add caching
  to 6 previously uncached endpoints (news, etf, filings) with appropriate TTLs
- Migrate all @validator to @field_validator (Pydantic v2), deduplicate validation
  logic into shared functions in validators.py
- Fix datetime.utcnow() → datetime.now(timezone.utc), remove unused uuid import
- Convert ErrorLogResponse class Config → model_config = ConfigDict(...)
- Add health check exception logging instead of silent pass
- Add data_source indexes to PriceData and FinancialData tables
- Initialize Alembic with async engine configuration
- Add persistent HTTP sessions for SEC client (aiohttp) and FRED proxy (httpx)
- Add response_model schemas for Alpaca bars/intraday and news-only/social-only

Add Alpaca-specific DB table and Redis caching for Alpaca/FINRA endpoints

Separate Alpaca price data into dedicated AlpacaPriceData table to avoid
UniqueConstraint('ticker', 'date') conflicts with Yahoo Finance PriceData.
Add Redis caching (build_cache_key/get_cached_response/set_cached_response)
to 3 Alpaca endpoints and 2 FINRA query endpoints with appropriate TTLs.
