Add template-specific command execution for Docker containers

[Copilot]

Description

Adds one-click command execution for running containers based on their detected template type. Commands are pre-configured per template (Django, Flask, FastAPI, React, Node.js, Python, Go) and validated against a whitelist before execution.

Core Changes

Template Detection & Commands

• Auto-detects template from Dockerfile content (keywords: django, flask, uvicorn, node, etc.)
• TEMPLATE_COMMANDS dict in models.py defines allowed commands per template
• Build.detected_template and Build.available_commands properties

Execution Pipeline

• exec_command_in_container() in docker_utils.py: runs docker exec with 120s timeout
• execute_container_command view: validates command against template's whitelist, rejects unauthorized commands
• /builds/<build_id>/execute-command/ POST endpoint

UI

• Quick Commands card in build_detail.html when container is running
• Real-time output display with exit code badges
• Template type badge in container list
• Uses textContent and FormData to prevent XSS

Command Examples

Django: python manage.py test, python manage.py migrate, python manage.py check --deploy
Flask: python -m pytest -v, pip list
React: npm test -- --watchAll=false, npm run build
Node.js: npm test, npm run lint, node --version

Security

• Commands validated against template whitelist - arbitrary execution blocked
• XSS prevented via DOM manipulation instead of innerHTML
• All command attempts logged with warning for unauthorized attempts
• CodeQL scan: 0 vulnerabilities

Type of Change

• New feature (non-breaking change that adds functionality)
• Test addition/modification

How Has This Been Tested?

• Unit tests
• Manual testing

Test Configuration:

• Python version: 3.12
• Django version: 5.0+
• Operating System: Linux

Tests Added:

• Template detection for all supported types
• Command whitelist validation
• Authorized vs unauthorized command execution
• XSS prevention verification

Additional Notes

Command execution requires:

1. Container status = running
2. Command in template's whitelist
3. User authenticated

Failed commands return exit code and error output. Timeout prevents resource exhaustion.

<issue_title>Ajouter des commandes supplémentaires communes pour chaque template de Docker</issue_title>
<issue_description>Par exemple, pour le template de Django, il pourrait y avoir des boutons pour effectuer une liste de commande courante, comme python manage.py test, disponible pour être lancée sur tous les docker actifs qui suivent ce template.

Suggère des commandes supplémentaires pour le template django (autre que runserver) et suggères-en aussi pour les autres templates. </issue_description>
