docs: remove all Coolify references from codebase

Replace Coolify with Docker Compose throughout documentation.
The project never used Coolify - a removal script was created but
never executed, leaving incorrect documentation.

Changes:
- Delete 13 heavily Coolify-focused docs files
- Update ~30 files replacing Coolify → Docker Compose
- Remove obsolete removal script
- Fix deployment references in active and archived projects
