fix(src/djinit/templates/project): update template placeholders and dependency references

New Features
- Replace double‑curly placeholder syntax with direct variable usage in justfile and procfile templates.

Enhancements
- Change psycopg2-binary to psycopg[binary] in pyproject.toml template.
- Update ruff.isort known‑first‑party from project_name to module_name.
- Adjust server commands to reference module_name placeholder and use variable syntax directly.

Bug Fixes- Fix placeholder expansion in dev‑server, makemigrations, install, and remove commands.
- Correct requirements generation script to handle missing pyproject.toml gracefully.
- Resolve incorrect variable substitution in gunicorn bind commands and worker count references.
