• Updated DF (patched) to Dec-25, released ver44.0.0 #53

This brings us up to the version45 release, this commit here and this apache branch.

Patches due to tech debt (all slated as lower priority, and are lingering):

• fix: handle when the left side of the union has no fields (e.g. an empty projection)
  • until we fix our iox issue: https://github.com/influxdata/influxdb_iox/issues/12407
• chore: default=true for skip_physical_aggregate_schema_check, and add warn logging
  • until we chase down all warnings in our iox logs: https://github.com/influxdata/influxdb_iox/issues/12404

Patches due to upstream bugs:

• chore: skip order calculation / exponential planning
  • exponential planning DF bug: Exponential planning time (100s of seconds) with UNION and ORDER BY queries apache/datafusion#13748
