Introduces a full Trading Economics API pipeline that fetches, stores, and
queries economic events (NFP, CPI, rate decisions, etc.) so the backtester
can block trade entries within a configurable buffer window of high-impact
releases — reducing slippage and false signals.

Track granularity (M1/M5) through the pipeline so rows are
distinguishable after upload. Drop helper columns (tr, typical_price,
pv) from the feature DataFrame. Add SQL schema with composite PK on
(time, instrument, granularity).
