fix(signal_v1): load_dotenv Path depth — resolve web-ai/.env correctly

3 files had insufficient .parent count, resolving to signal_v1/.env
instead of web-ai/.env (which is where the actual env file lives).
Added one .parent each:
- config.py: parent.parent → parent.parent.parent
- analysis/macro.py: parent.parent.parent → parent.parent.parent.parent
- services/telegram_bot/runner.py: parent.parent.parent.parent → +1

watchlist_manager.py was already correct.
