Generate mandatory XLS forms programmatically

[Sujanadh]

Summary

This pull request introduces a new feature to generate mandatory XLS forms directly within the codebase. It modularizes the workflow, making it easier to manage and scale form generation tasks.

Features

Added a modular structure to generate XLS forms:

• mandatory_fields.py: Defines essential fields for all forms.
• digitisation_fields.py: Includes specific fields for digitization and verification processes.
• choice_fields.py: Handles choices required for mandatory fields.

Combined all components into a single pipeline to generate the final survey XLS form.

Key Improvements

Added submission_id caculation field to update entity property with latest submission_id.
Created a function standardize_xlsform_sheets which:

• checks for the columns, converts them to lower case
• removes any empty rows, and
• mainly checks the language labels

and creates a standard language label for any kind of label present in the user-defined xls form consequently making a standard xls form.

Update:

Actually, there was a way to have multiple submission_ids in a single entity just by concatenating it with a previous submission_id.

• updated the caculations of submission_ids to append previous submission_ids as well.

* updated the caculations of `submission_ids` to append previous `submission_ids` as well.

That's huge!!

We can easily have a disambiguation dialog to select the submission on the frontend then 🎉

💯 the workflow to choose - thanks for sticking to your guns and convincing me 😄

This PR is perfect for now, but we should definitely consider moving all these translations out into a separate YAML or something, at some point.

This way users could update the translations via weblate or transifex (we will add this for UI translations soon anyway)

[Sujanadh]

Yeah I also thought about that 👍

[spwoodcock]

Lovely docstring 👍

[spwoodcock]

🙌😁

If you can translate the other columns into Nepali then feel free to add them! (might help Tokha I imagine)

[spwoodcock]

Merge whenever 👍

You can make and push a new release too

cz bump --check-consistency
git push
git push --tag

#then release on github

I will get back to it sooner.
