feat: migrate resource management to utopia-php/di container

This backports the DI container integration from the 0.34.x branch to 0.33.x:

- Replace internal array-based resource management with Utopia\DI\Container
- Update constructor to accept optional Container parameter
- Add getContainer() and getRequestContainer() methods
- Change setResource() from static to instance method
- Update getResource() and getResources() to use Container scope
- Create request-scoped containers for each request lifecycle
- Update all internal calls to use new container-based API
- Remove static resource callbacks array
- Update adapters to remove static Http::setResource() calls
- Update tests to use container-based approach

BREAKING CHANGE: Http::setResource() is now an instance method instead of static.
Users should now call $http->setResource() instead of Http::setResource().
