chore: Update column order for ELABDATADISP to exclude node/state/calc_err

Updated get_column_order() for elabdatadisp table to return only the
columns that are now stored separately:
- id_elab_data
- unit_name
- tool_name_id
- event_timestamp
- measurements (includes node_num, state, calc_err keyed by node)
- created_at

Removed: node_num, state, calc_err, updated_at (not used after consolidation)

This matches the schema defined in schema_transformer.py where these fields
are noted as being stored in the JSONB measurements column.
