Remove singular x-appwrite method metadata

[ChiragAgg5k]

What does this PR do?

Stops emitting singular x-appwrite.method from OpenAPI operations. SDK method names now come from the service-qualified operationId; plural x-appwrite.methods aliases remain unchanged.

before: operationId: accountCreate, x-appwrite.method: create
after:  operationId: accountCreate

Uses appwrite/sdk-generator 4.0.2, released by appwrite/sdk-generator#1804.

Test Plan

• vendor/bin/phpunit tests/unit/SDK/Specification/FormatTest.php — 20 tests, 103 assertions
• composer update appwrite/sdk-generator --with-dependencies --minimal-changes — updated the lock file to 4.0.2
• composer lint src/Appwrite/SDK/Specification/Format/OpenAPI3.php tests/unit/SDK/Specification/FormatTest.php
• composer refactor:check
• Generated current 1.9.x client, server, and console specs; canonical diffs contained only removal of 149, 554, and 610 singular fields respectively
• Generated every SDK target through php app/cli.php sdks --platform=* --sdk=* --version=1.9.x --git=no --mode=examples using appwrite/sdk-generator 4.0.2

Greptile Summary

This PR removes the deprecated singular x-appwrite.method metadata so SDK method names come from service-qualified OpenAPI operationId values, while preserving plural aliases.

• Removes singular method metadata and its multi-method suffix handling from the OpenAPI 3 formatter.
• Updates the formatter test expectations for multi-method routes.
• Bumps appwrite/sdk-generator from 4.0.1 to 4.0.2 for the corresponding generator behavior.

Confidence Score: 5/5

The PR appears safe to merge, with the formatter and coordinated generator dependency consistently adopting operation IDs as the SDK method-name source.

No concrete blocking or independently actionable non-blocking issue remains in the changed formatter, test, or dependency lock entry.
