refactor: change debugger port from 5679 to 3003

Updates the debugger service to use port 3003 instead of 5679 across
all configuration files, documentation, and code references. This aligns
the debugger with the other windmill-extra services which use ports
3001 (LSP) and 3002 (Multiplayer).

Changes:
- docker-compose.yml: Update port exposure and add DEBUGGER_PORT env
- docker/entrypoint-extra.sh: Change default port from 5679 to 3003
- debugger/dap_debug_service.ts: Update default port in code and docs
- debugger/README.md: Update port documentation
- debugger/test_debug_service.ts: Update test URLs
- docker/test_windmill_extra.ts: Update test configuration
- .github/workflows/publish_extra.yml: Update test container ports
- frontend/src/lib/components/debug/*: Update frontend examples and defaults
