FIX: Tableau writer schema mismatch with Bus schema

[huangh]

The bus_schema defined in the Tableau writer needs to be in the same order as the polars schema from the Bus_Performance_Manager outputs in bus_vehicle_events.

Changes:

• Re-aligns the order of the schema
• Add a select statement to ensure the read in Table is in the correct schema order (2nd line of defense)
• Refactor conversions for tableau analysis out into a new method for easy testing and verification
• Add new analysis scripts that help check for issues in Tableau/parquet writing
