Dynamically Generate TypeScript DB Models, Transcript Model, and other Constants

## Idea / Feature

Dynamically generate TypeScript object definitions from `cdp-backend` Python DB models.

## Use Case / User Story

As a developer I want to be able to add, remove, or update a database model in a single location rather than multiple.

## Solution

Add a script to `cdp-backend` that when ran will generate a TypeScript package of the database models + extras that we can push to npm on new version push.

## Alternatives

## Stakeholders

Backend maintainers
Frontend maintainers

## Major Components

* [ ] Database models TypeScript generation
* [ ] Transcript File Model TypeScript generation
* [ ] Database "ModelField" Python and TypeScript generation
* [ ] Database constants TypeScript generation
* [ ] script added as bin script to `cdp-backend`
* [ ] task added to CI building and testing that attempts to generate these models on PR push / main build
* [ ] task added to CI main building / publish job that pushes the generated TypeScript package dir to npm

## Dependencies

## Other Notes

No se nombran archivos ni pruebas específicos. Empieza por localizar los modelos de base de datos de Python, los puntos de entrada de bin-script de cdp-backend y los trabajos de compilación y publicación de CI; se considera terminado cuando los modelos y las constantes de TypeScript generados se prueban en las compilaciones y el paquete se publica según lo especificado.
