fix: correct get_db_path() usage to pass base database path

The get_db_path() function requires a base_db_path argument
to properly resolve PROD vs DEV database paths. Updated all
calls to pass "data/jobs.db" as the base path.

Changes:
- agent_tools/tool_trade.py: Fix 3 occurrences (lines 33, 113, 236)
- tools/price_tools.py: Fix 2 occurrences in new database functions
- Remove unused get_db_path import from tool_trade.py

This fixes TypeError when running simulations:
  get_db_path() missing 1 required positional argument: 'base_db_path'

The get_db_connection() function internally calls get_db_path()
to resolve the correct database path based on DEPLOYMENT_MODE.
