Bug: `evo-objects` rejects PyArrow `large_string` values

[davidknight-seequent]

Bug Description

evo-objects rejects PyArrow large_string values produced by pandas 3 during dataframe upload.

When uploading dataframes through evo-objects, string columns can be inferred by PyArrow as large_string instead of string. evo-objects currently treats large_string as unsupported and raises a TypeError during table format detection and category upload.

Observed Error

Unsupported column type large_string from DataType(large_string)

Impact

Any workflow that calls save_dataframe or upload_dataframe on a dataframe containing text columns may fail if PyArrow infers those columns as large_string.

This affects:

• String attribute uploads
• Lookup table uploads for category attributes
• Any table format inference path that relies on ArrowTableFormat.from_schema

Acceptance Criteria

• Related functionality is unaffected
• A test case is added to prevent regression
