Expose primary_name_attribute in TableInfo, fix prodev example E2E

SDK changes:
- _get_entity_by_table_schema_name now selects PrimaryNameAttribute and
  PrimaryIdAttribute from EntityDefinitions
- _create_table returns primary_name_attribute in its result dict
- TableInfo model includes primary_name_attribute and primary_id_attribute
  fields with legacy key access
- Fixes #148: tables.create() now exposes the primary column logical name

Example changes:
- prodev_quick_start.py uses result.primary_name_attribute from tables.create()
  to construct correct record payloads (fixes the demo_*_name column error)
- Both examples verified E2E against live Dataverse
