TPTBusiness 919a44a4b8 fix(auto-fixer): add five new factor code fixes for groupby/apply errors ...

1. groupby(level=['instrument','date']) → get_level_values() — string level
   names like 'date' don't exist in the (datetime, instrument) MultiIndex;
   replaced with get_level_values(0).normalize() + get_level_values(1).

2. groupby(level=['date','instrument']) — symmetric fix for reversed order.

3. groupby(level=['instrument']) → groupby(level=1) — single string level.

4. groupby(level=N)['col'].apply(lambda) → transform(lambda) — apply() on a
   grouped Series prepends an extra index level, causing index shape mismatch
   when assigned back; transform() preserves the original index.

5. df.loc[instrument] DateParseError fix (instrument_loc_multiindex) — already
   committed, adding supporting tests for groupby(level=['instrument','date']).

Adds 5 new tests (TestGroupbyLevelStringNames, TestGroupbyApplyToTransform)
— total 28 tests, all passing.
