* fix: add copy_rates_from_pos_as_df fallback in fetch_latest_closed_rates_for_trading_client
Mt5DataClient (returned by create_trading_client) exposes copy_rates_from_pos_as_df,
not fetch_latest_rates_as_df. Adds a fallback path that resolves the granularity string
to an integer timeframe via parse_timeframe, fetches count+1 bars from start_pos=0,
and applies the same drop_forming_rate_bar + tail(count) logic so callers that use
the client returned by create_trading_client no longer need a compatibility shim.

* Bump version to v1.0.3
* fix: hoist parse_timeframe before dispatch and add invalid-granularity test
Hoisting parse_timeframe(granularity) before the fetch_latest_rates_as_df /
copy_rates_from_pos_as_df dispatch ensures invalid granularity strings fail
consistently on both paths with a clear ValueError, rather than only when
the fallback branch is taken.
Adds test_copy_rates_from_pos_fallback_raises_on_invalid_granularity to pin
the early-validation contract and confirm the underlying method is never called.
