As a Dev, I'd like the query modules to utilize an ORM plugin

## Context

The query modules for all project served as a interface to execute Database queries. It was built as an ORM. However, based on a dev request, we would like to seperate ourselves from writing manual SQL queries and implement a prebuilt ORM toolkit to simplify database interactions and improve maintainability. This will help in reducing the complexity of manually written queries and ensure easier handling of database relationships across different objects.

## Proposed technology
- [SQL Alchemy](https://www.sqlalchemy.org/)
- [PostgREST](https://docs.postgrest.org/en/v12/)

## Acceptance Criteria:
- An ORM plugin audit has been performed with a relevant ADR
- Integrate a suitable ORM plugin within the ``db/queries/`` directories.
- Ensure that all existing query modules are refactored to use the ORM methods.
- ORM should handle relationships (if applicable) between different objects and provide built in models of entities
- Ensure proper documentation and examples are provided for developers using the query modules with the ORM
