Use DI resource container in executor

[ChiragAgg5k]

Summary

• switch executor bootstrap resource registration from Http::setResource() to a shared Utopia\DI\Container
• pass the DI container into Http so framework-owned runtime resources stay in the HTTP layer
• point Composer at the utopia-php/framework and utopia-php/di development branches required for this integration

Notes

• composer.lock now resolves utopia-php/framework from feat/use-di-resource-container
• composer.lock now resolves utopia-php/di from chore/extract-http-di-resources
• the lockfile also includes a few upstream package bumps from the Composer update

Verification

• php -l app/init.php
• php -l app/http.php
