Feat/dv 1637/database schema centralization

[nicov-iov]

This pull request introduces support for a new prisma git submodule, updates documentation to guide users on cloning and initializing submodules, and ensures both the Docker build process and CI workflows properly handle submodules. These changes ensure that the application always has access to the required external schema and related files from the prisma repository.

Indexer using the new prisma submodule:

Note: Since the prisma submodule is using the latest prisma schema from the db refactor PR #248, this branch was temporarily merged with that PR so the indexer core logic supports it for the tests. This PR only includes the submodule logic.

Submodule Integration:

• Added the prisma submodule to the repository by updating .gitmodules and including the submodule commit reference in prisma/. [1] [2]
• Updated the Docker build process to initialize and update submodules, ensuring the container has the necessary schema files. (Dockerfile)
• Modified the CodeQL CI workflow to recursively checkout submodules during the code checkout step. (.github/workflows/codeql.yml)

Documentation Updates:

• Updated README.md to instruct users to clone the repository with submodules and provided guidance for those who have already cloned without submodules.
• Clarified in README.md that npx prisma generate uses the schema from the prisma submodule.
