feat: SDK update for version 0.14.0

[ChiragAgg5k]

This PR contains updates to the SDK for version 0.14.0.

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
• Breaking: Execution.functionId is replaced by resourceId and resourceType, covering function and site executions
• Added: Cloudflare, Resend, and Hugging Face 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 Rust SDK to Appwrite API response format 2.0.0 and promotes crate version 0.14.0.

• Adds Cloudflare and Resend OAuth provider contracts and project update methods.
• Adds transaction IDs to DocumentsDB and VectorsDB document creation.
• Updates dedicated-database credential rotation to return asynchronous operations.
• Renames the TablesDB cutover method and route and expands models and enums for the new API.

Confidence Score: 4/5

The nullable credential-generation field must be fixed before merging because it makes valid dedicated-database responses fail to decode.

The new model requires an integer for a field explicitly documented as null before credential rotation is initialized, and the shared transport directly deserializes that response into the model.

Important Files Changed

Filename	Overview
src/client.rs	Updates global response-format and SDK-version headers to 2.0.0 and 0.14.0.

src/services/documents_db.rs	Adds optional transaction IDs to single and bulk document creation payloads.
src/services/vectors_db.rs	Adds optional transaction IDs to single and bulk vector-document creation payloads.
src/services/project.rs	Adds Cloudflare and Resend OAuth2 configuration update operations consistent with sibling providers.
src/services/tables_db.rs	Renames the migration cutover operation and updates its endpoint to the plural route.
src/services/mongo.rs	Changes credential rotation to return an asynchronous dedicated-database operation.
src/services/mysql.rs	Changes credential rotation to return an asynchronous dedicated-database operation.
src/services/postgresql.rs	Changes credential rotation to return an asynchronous dedicated-database operation.

### Issue 1
src/models/dedicated_database.rs:54-57
**Nullable generation breaks decoding**

When a dedicated database has not initialized credential rotation, `credentialGeneration` is null, but this required `i64` cannot represent null, causing otherwise successful dedicated-database responses to return deserialization errors.

```suggestion
    /// Committed generation of the primary connection credentials. Null until the
    /// rotation contract has been initialized.
    #[serde(rename = "credentialGeneration")]
    #[serde(skip_serializing_if = "Option::is_none")]
    pub credential_generation: Option<i64>,
```
