Closes#11
`starter_rating`, `relief_rating`, and `closer_rating` were hardcoded
stubs (5/5/None) in `create_pitching_card`. The chosen `PitcherArchetype`
already carries these values; now they are propagated through `card_data`
when the pitcher workflow builds its initial dict and consumed correctly
when writing the pitching card record to the database.
