Fix: Updated measure "PA" field name to "IOU_AC_Territory" in CET example file

The example CET upload file has been updated to align with the current CET specification.

What changed

• The field previously labeled PA in the example CET measure.csv has been renamed to IOU_AC_Territory.

Where

• The update applies to the example file in cet_example_input.zip, which is available on the CET specification page:
  https://cedars.cpuc.ca.gov/cet_ui/spec/

Why

• This field name had already been updated in the CET and metadata files, but it was missed in the example upload file.

• The example file now matches the current specification to avoid confusion when preparing CET and Filing uploads.

Files affected

• cet_example_input.zip (measure CSV inside the example upload)
