Export payroll and resolve employee sign-off disputes

Approved payroll can be mapped to generic, ADP, Gusto, or Paychex earnings codes, while each employee can sign the immutable run or open one reviewable dispute.

Where: Team -> Pay rules & exports; Payroll run -> Sign-off

1. Map the payroll provider's earnings codes and each tech's provider employee ID.
2. Preview and approve the payroll run using the established payroll workflow.
3. Export the provider CSV; WaterMark prepares the file and never claims it submitted payroll.
4. If a tech disputes an approved run, review the note and resolve it; any dollar correction belongs on the next payroll run.
