fix(dashboard): remove dependency on `pandas`

[zilto]

The dlt Dashboard, installed via dlt[workspace] shouldn't depend on pandas. Pandas is a heavy dependency and is not required. The marimo UI can render pyarrow tables directly. Also, having the duckdb group in ibis-framework[duckdb] installs pandas and numpy as dependencies. They are not required for ibis to work.

Ideal dependencies would be be:

workspace = [
  "duckdb",
  "ibis-framework",
  "pyarrow",
  "pyarrow-hotfix",
  "marimo",
]
