This pull request introduces middleware to improve compatibility between the frontend and backend in unified mode, and updates the project version numbers to reflect the new changes.

Middleware for unified mode compatibility:

• Added a new StripApiPrefixMiddleware class in flowfile/web/__init__.py that strips the /api prefix from incoming requests. This ensures that API requests from the frontend (which use /api/ as a base URL) are correctly routed to the backend, particularly in unified mode where the app is run outside Docker or without an nginx reverse proxy. The middleware is added to the FastAPI app during initialization.

Version updates:

• Bumped the version number in pyproject.toml from 0.7.1 to 0.7.2 to reflect the new middleware addition.
• Updated the version in flowfile_frontend/package.json from 0.7.1 to 0.7.2 for consistency across the project.
