Change to HTTP localhost

[javidahmed64592]

This pull request removes support for built-in SSL certificate generation and HTTPS, migrating the project to use plain HTTP on port 8000 by default. All documentation, configuration, and code related to SSL/TLS, certificate management, and HTTPS endpoints have been updated or removed to reflect this change. The pull request also updates dependencies and simplifies some config files.

Migration from HTTPS to HTTP and removal of SSL certificate support:

• Removed certificate generation and management: The certificate_handler.py file and the CertificateConfigModel have been deleted, and all references to SSL certificates and related configuration are removed from the codebase and documentation. (python_template_server/certificate_handler.py [1] python_template_server/models.py [2] configuration/config.json [3] .github/copilot-instructions.md [4] [5] [6] README.md [7] [8] docs/source/server.rst [9]
• Changed default protocol and port: All references to https://localhost:443 are now http://localhost:8000, and the default port is set to 8000 in environment variables, Docker, and documentation. (.env.example [1] .github/workflows/docker.yml [2] docker-compose.yml [3] [4] Dockerfile [5] README.md [6] RELEASE-NOTES.md [7] docs/source/server.rst [8] [9] docs/source/smg.rst [10] .github/copilot-instructions.md [11] [12] [13]
• Updated health checks and Docker configuration to use HTTP and port 8000. (docker-compose.yml [1] [2] Dockerfile [3]

Documentation and config cleanup:

• Removed references to certificate handling and HTTPS from documentation, code comments, and config files. (.github/copilot-instructions.md [1] [2] [3] [4] README.md [5] [6] docs/source/server.rst [7] [8] [9] docs/source/smg.rst [10] .dockerignore [11]
• Simplified CORS config formatting in configuration/config.json. (configuration/config.json configuration/config.jsonL8-R11)

Dependency updates:

• Updated several dependencies to their latest versions in pyproject.toml, including cryptography, fastapi, uvicorn, and pytest-env. (pyproject.toml pyproject.tomlL21-R35)

Other minor cleanups:

• Removed unused or obsolete volumes and code references related to certificates. (docker-compose.yml [1] [2] .dockerignore [3]
• Minor docstring and comment cleanups in startup code. (python_template_server/main.py python_template_server/main.pyL46-R46)

These changes collectively shift the template to a simpler, HTTP-only setup, making it easier to run locally and in containers without SSL/TLS management.
