lebaudantoine 3fd5a4404c (backend) add application model with secure secret handling
We need to integrate with external applications. Objective: enable them to
securely generate room links with proper ownership attribution.

Proposed solution: Following the OAuth2 Machine-to-Machine specification,
we expose an endpoint allowing external applications to exchange a client_id
and client_secret pair for a JWT. This JWT is valid only within a well-scoped,
isolated external API, served through a dedicated viewset.

This commit introduces a model to persist application records in the database.
The main challenge lies in generating a secure client_secret and ensuring
it is properly stored.

The restframework-apikey dependency was discarded, as its approach diverges
significantly from OAuth2. Instead, inspiration was taken from oauthlib and
django-oauth-toolkit. However, their implementations proved either too heavy or
not entirely suitable for the intended use case. To avoid pulling in large
dependencies for minimal utility, the necessary components were selectively
copied, adapted, and improved.

A generic SecretField was introduced, designed for reuse and potentially
suitable for upstream contribution to Django.

Secrets are exposed only once at object creation time in the Django admin.
Once the object is saved, the secret is immediately hashed, ensuring it can
never be retrieved again.

One limitation remains: enforcing client_id and client_secret as read-only
during edits. At object creation, marking them read-only excluded them from
the Django form, which unintentionally regenerated new values.
This area requires further refinement.

The design prioritizes configurability while adhering to the principle of least
privilege. By default, new applications are created without any assigned scopes,
preventing them from performing actions on the API until explicitly configured.

If no domain is specified, domain delegation is not applied, allowing tokens
to be issued for any email domain.
