add sub account deletion

[oshchyhol]

Motivation

The API is getting DELETE /api/organizations/{organization_id}/sub_accounts/{sub_account_id}. The SDK has list and create for sub accounts but no way to delete one.

Changes

• SubAccountsApi.delete(sub_account_id) – sends the delete request and returns a DeletedObject with the given id
• _api_path takes an optional sub_account_id and appends it to the path
• unit tests for the 204 response and for 401, 403, 404 and 429 errors
• examples/organizations/sub_accounts.py deletes the sub account it creates
• README bullet lists the supported sub account operations

How to test

With MAILTRAP_API_KEY (token with sub account management permissions for the organization) and MAILTRAP_ORGANIZATION_ID set:

• client.organizations_api.sub_accounts.delete(<existing sub account id>) → returns DeletedObject(id=<that id>), the sub account is gone from get_list()
• call delete again with the same id → raises APIError with a 404 message
• delete with a sub account id from another organization, or with a token without sub account management permissions → raises APIError with a 403 message
• delete with an invalid token → raises APIError with a 401 message
• python examples/organizations/sub_accounts.py → prints the list, the created sub account and the deleted object for it
• README "Organizations API" section shows Sub-Accounts management (list, create, delete) linking to the example

Companion PRs

• backend endpoint (must deploy first)
• document the delete organization sub account endpoint mailtrap-openapi#56 – spec
• add sub account deletion mailtrap-nodejs#159 – nodejs SDK
• add sub account deletion mailtrap-ruby#130 – ruby SDK
• add sub account deletion mailtrap-php#80 – php SDK
• add sub account deletion mailtrap-java#75 – java SDK
• add sub account deletion mailtrap-dotnet#259 – .NET SDK
• add sub account deletion mailtrap-go#30 – go SDK
• add sub-account deletion to the CLI mailtrap-cli#15 – CLI
• add delete-sub-account tool mailtrap-mcp#144 – MCP server

Caveat: merge and release only after the backend change ships; the endpoint is not in production yet.

Walkthrough

The Organizations API adds sub-account deletion. The resource builds item-specific endpoints and returns a DeletedObject. Unit tests cover error and success responses. The example and README now show deletion support.

Changes

Sub-account deletion

Layer / File(s)	Summary
Delete API implementation mailtrap/api/resources/sub_accounts.py	SubAccountsApi.delete calls the sub-account delete endpoint and returns a DeletedObject. _api_path now supports optional sub-account IDs.
Delete API validation tests/unit/api/organizations/test_sub_accounts.py	Tests cover unauthorized, forbidden, not-found, and rate-limit errors. A success test verifies the returned DeletedObject ID.
Example and documentation updates examples/organizations/sub_accounts.py, README.md	The example deletes the created sub-account and prints the result. The README lists creation and deletion support.

Estimated code review effort: 2 (Simple) | ~10 minutes
