* OAuth Implementation based on middleware

Signed-off-by: Volodymyr Panivko <sveneld300@gmail.com>

* Address PR review feedback for OAuth middleware

* Apply php-cs-fixer to satisfy QA

* Use Mcp exception classes in OAuth middleware

* Refactor OAuth HTTP stack and add Microsoft example policies

* Fix QA PHPStan findings in OAuth examples and auth middleware

* Require OIDC discovery in JWKS provider and refine OAuth proxy behavior

* Remove local development docker artifacts from VCS

* Revert .gitignore changes for local docker files

* Fix body retrieval in OAuthRequestMetaMiddleware for proper string conversion

* Address OAuth PR review feedback and align example configs

* Fix QA style issues and add authorization docs

* Fix PHPStan typing issues in OAuth middleware

* Remove duplicate Middleware namespace, consolidate under Http\Middleware

Remove old Mcp\Server\Transport\Middleware\ classes that were duplicated
in Mcp\Server\Transport\Http\Middleware\ and Http\OAuth\. Update docs
to reference the correct namespaces.

* Address PR review: replace Throwable catch with specific exceptions, add JSON_THROW_ON_ERROR

- JwtTokenValidator: replace catch(\Throwable) with explicit
  \InvalidArgumentException|\UnexpectedValueException|\DomainException,
  letting RuntimeException from JwksProvider propagate as infrastructure errors
- OAuthProxyMiddleware: add \JSON_THROW_ON_ERROR to json_encode for metadata response
- Update tests to expect RuntimeException for JWKS infrastructure failures
