Simplify DI container API by removing Dependency class usage (#228)

* chore: upgrade utopia-php/servers to 0.3.* and utopia-php/di to 0.3.*

- Replace all Dependency class usage with new Container::set(string, callable) API
- Add executeHook() method to Http class to replace removed Container::inject()
- Update Route to call parent::__construct() for Hook's new constructor
- Update all test files and examples to use new DI API
- Resolves breaking changes from DI dropping Dependency/Injection classes

* fix: set request factory on cloned context in testCanRunRequest

The test was setting the request factory on $this->context instead of the
cloned $context, so run() never received the HEAD request. Fixed the
target container and updated the assertion to match actual HEAD behavior.

* refactor: rename $context to $container in Http.php for consistency

Consolidates the DI variable naming to $container throughout, avoiding
confusion with the legacy array-based context pattern.

* refactor: use child containers instead of clone for request scoping

Replace `clone $this->container` with `new Container($this->container)`
to use the parent-child delegation pattern introduced in utopia-php/di
0.3, consistent with how Base::prepare() already creates scoped containers.

* test: add container isolation tests to verify no state bleed between requests

- testContainerIsolationBetweenRequests: verifies child containers resolve
  their own request/response independently and parent is not polluted
- testContainerIsolationForErrors: verifies error state from one request
  does not leak into subsequent requests

* fix: remove unused \$name key variable in foreach loop

Drops the unused key variable from the getInjections() foreach at
Http.php:175 to silence static analysis warnings.

* fix: remove unreachable duplicate OPTIONS handling block

The elseif branch for REQUEST_METHOD_OPTIONS at line 661 was dead code —
OPTIONS requests are already handled and returned earlier (lines 628-657).
Removing the duplicate simplifies the control flow.
