Fix tools wiring so agents actually call yfinance/ddgs/pandas-ta

The first deploy passed tools={} to WatchlistRunner, which meant every
agent got tools=[] and couldn't look up real prices. The LLM reasoned
from its training data and hallucinated a plausible-looking entry
price ($192 vs actual $293 for AAPL). Import the 10 tool functions
from the tools package and dispatch them to the right agent via
crew_tools so get_price_change / get_financials / etc. actually run.
