Derive SDK method names from operation IDs

[ChiragAgg5k]

Summary

• derive service-local SDK method names from operationId and the matching operation tag
• assign synthetic service-qualified operation IDs to x-appwrite.methods aliases
• remove singular x-appwrite.method reads, writes, and E2E fixture fields

accountCreate + account              -> create
databasesListDocuments + databases  -> listDocuments
oauth2Authorize + oauth2            -> authorize

Closes #1790.

Verification

• Generated every SDK target from current Appwrite 1.9.x client, server, and console specs with singular x-appwrite.method removed
• Compared each generated tree with an origin/main same-spec baseline; outputs were identical for all three platforms
• composer refactor:check
• composer lint-twig
• vendor/bin/phpunit tests/e2e/PHP83Test.php (1,401 assertions)
• vendor/bin/phpunit tests/e2e/CLIGo126Test.php (5,407 assertions)
• Generated CLI: go build ./..., go vet ./..., go test ./..., and gofmt check

Greptile Summary

The PR replaces x-appwrite.method metadata with service-local method names derived from operation IDs and matching tags.

• Adds shared operation-ID method-name derivation to the base language class.
• Assigns service-qualified IDs to aliased operations.
• Migrates CLI command-surface naming to the shared derivation.
• Updates the OpenAPI fixture to remove singular method metadata and exercise aliases.

Confidence Score: 5/5

The PR appears safe to merge because no blocking failure remains within the eligible follow-up-review scope.
