fix(ta): computed name issue

seeing an error in sentry where polars is unable to infer the schema
because the computed_name is null for a bunch of testruns

2 things:
- i don't want the computed name to be null (in the future this logic
  should live in the test results parser lib)
- the polars schema should've been verbose about types from the start
  to avoid schema inference issues
