feat: edi template instrumentation

[blaggacao]

This PR adds instrumentation to work with EDI Templates (such as E-Invoices and E-Payroll and similar).

It is designed to support a mixed development model consisting of:

• Quick prototyping via the Backend
• Detailed implementation of context and submit logic via code files in an editor

It sets up the EDI Template and auxiliar doctypes to anchor the templating logic for each desired transaction doctype.
