Refactor hitter tab layout and enhance position selection in Streamlit app

- Reduced the number of columns in the hitter tab layout for improved organization.
- Replaced single select for positions with a multiselect option, allowing users to choose between 'All' or 'Specific' positions.
- Updated logic to handle position selection based on user input, enhancing interactivity.
- Adjusted loading spinner duration for league baselines to improve user experience during data retrieval.
