30M Scalping Strategy with Debug Logs

What’s changed

Spot‑only: all short logic removed—only long entries and exits are generated.

Logging: uses log.info() to send entry/exit details (timestamp, price, ATR, RSI) to the Pine Logs console.

Clean & concise: core scalp logic (EMAs, RSI, MACD, volume, ATR SL/TP) remains intact.
