AI Description

This pull request introduces several changes to the Makefile, primarily focused on enhancing the testing, linting, and database management processes. The changes are organised into sections for the backend and frontend, with the backend section being newly added.

Backend

• Testing & Linting: The PR adds a new section for testing and linting, including commands for running unit tests, community tests, and integration tests. It also introduces commands for type checking (typecheck), linting (lint), and linting with automatic fixes (lint-fix).
• Database Management: A new test-db command is added to stop, remove, and restart the test database.
• Setup: The install command is introduced for installation with the dev option.

Frontend

• Coral Web: The PR adds commands for formatting (format-coral), generating clients (generate-client-coral), installing (install-coral), and building (build-coral) the Coral Web interface.
• Assistants Web: The format-web and build-web commands are moved from the backend to the frontend section, ensuring a clear separation of concerns.

Good changes!

I haven't reviewed the README recently, but are there any changes we should be making to the documentation now that we have some new commands in the Makefile here for people to use?
