Gud Boi 19c6d98e6d Normalize provider OHLCV for `NativeDB`
IB history frames omit the derived `index` and append `count`.
Normalize provider data to durable names, order, and dtypes before
merge, and reject fractional epoch truncation.

Also,
- map canonical storage fields into provider-specific SHM on reload
- select Polars columns by name instead of position
- exercise first-start and restart through actor, SHM, and Parquet
