Add dynamic field name to cat4 error messages

[jtimpe]

Description:
Per Alex's comment on #2879, cat4 error messages should include the field name. The value has been hard-coded in as part of #2879's changes, but the string should dynamically insert the relevant field name (and/or the field's friendly name, if applicable) from the schema instead.

Acceptance Criteria:

• Cat4 error messages include the field name and/or friendly_name, dynamically pulled from the schema stored alongside each record
• Testing Checklist has been run and all tests pass
• README is updated, if necessary

Tasks:

• Get the field from the schema into CaseConsistencyValidator
• Dynamically replace the field name into the cat4 error message string. The error should stay the same. [Design Deliverable] Update error audit to include cat 4 plain language fixes  #2968 covers research to update the string based on feedback
• Make a util function to format the name/friendly_name for consistency across cat4 error messages, e.g.,

  TANF-app/tdrs-backend/tdpservice/parsers/validators.py

  Line 257 in c2c465f

  def format_error_context(row_schema, friendly_name, item_num):

• Run Testing Checklist and confirm all tests pass
• Test Case: upload a file with cat4 errors, field name remains in error string
