[ChiragAgg5k]

This PR contains updates to the SDK for version 30.0.0.

What's Changed

• Stable release of the dedicated database APIs: mysql, postgresql, mongo, documentsDB, and vectorsDB services, previously released as release candidates
• Breaking: tablesDB.cutoverMigration is renamed to tablesDB.createCutover
• Added: Cloudflare and Resend OAuth providers
• Added: usageAggregateOnlyMetrics on the BillingPlan model
• Fixed: transactionId is accepted again by documentsDB and vectorsDB createDocument and createDocuments
• Updated: X-Appwrite-Response-Format is now 2.0.0
• Updated: FrameworkAdapter.fallbackFile is now optional

Greptile Summary

This release updates the PHP SDK to Appwrite API response format 2.0.0 and promotes the dedicated database APIs to their stable surface.

• Adds Cloudflare and Resend OAuth provider support and related models and enums.
• Restores transaction IDs for DocumentsDB and VectorsDB create operations.
• Renames the TablesDB cutover operation and updates dedicated-database credential rotation to return an asynchronous operation.
• Updates generated models, documentation, examples, and service tests.

Confidence Score: 4/5

The nullable credential-generation state must be handled before merging because valid dedicated-database responses can otherwise fail model hydration.

DedicatedDatabase documents credentialGeneration as null before initialization but passes it into a required int constructor parameter, causing a TypeError on that valid lifecycle state.

src/Appwrite/Services/VectorsDB.php	Adds optional transaction IDs to vector document creation consistently with existing transaction-aware operations.
src/Appwrite/Services/Project.php	Adds Cloudflare and Resend OAuth update endpoints and provider-response dispatch.
src/Appwrite/Services/TablesDB.php	Renames the migration cutover method and updates it to the new plural endpoint.
src/Appwrite/Services/Mongo.php	Updates credential rotation to hydrate and return an asynchronous database operation.
src/Appwrite/Services/Mysql.php	Updates credential rotation to hydrate and return an asynchronous database operation.
src/Appwrite/Services/Postgresql.php	Updates credential rotation to hydrate and return an asynchronous database operation.

### Issue 1
src/Appwrite/Models/DedicatedDatabase.php:84
**Credential generation rejects null state**

If a dedicated database has not initialized its credential-rotation contract, the API can return a null `credentialGeneration`, but this property requires an `int` and hydration passes the value directly to it, causing a `TypeError` instead of returning the database model.
