This pull request includes significant changes to the api-description/web-api.swagger.yaml file, the pkg/account/api/api_key.go file, and several other files to refactor the API key retrieval process and improve the overall code structure. The most important changes include modifying the API endpoint method, updating the request and response schemas, and refactoring the related service and storage methods.

Changes to API endpoints and schemas:

• Changed the method of the /v1/account/get_environment_api_key endpoint from post to get and updated the response schema reference. (api-description/web-api.swagger.yaml)
• Updated the parameters for the /v1/account/get_environment_api_key endpoint to include apiKey as a query parameter instead of a body parameter. (api-description/web-api.swagger.yaml)
• Removed the accountGetAPIKeyBySearchingAllEnvironmentsRequest and accountGetAPIKeyBySearchingAllEnvironmentsResponse definitions and added the accountGetEnvironmentAPIKeyResponse definition. (api-description/web-api.swagger.yaml) [1] [2]

Refactoring service methods:

• Renamed the GetAPIKeyBySearchingAllEnvironments method to GetEnvironmentAPIKey and simplified the logic by removing the project and environment list retrievals. (pkg/account/api/api_key.go) [1] [2] [3]

Updating storage methods:

• Added the GetEnvironmentAPIKey and ListAllEnvironmentAPIKeys methods to the accountStorage interface and implemented them in the storage layer. (pkg/account/storage/v2/api_key.go, pkg/account/storage/v2/storage.go) [1] [2]
• Embedded new SQL queries for selecting environment API keys. (pkg/account/storage/v2/sql/api_key_v2/select_all_environment_api_keys_v2.sql, pkg/account/storage/v2/sql/api_key_v2/select_environment_api_key_v2.sql) [1] [2]

Mock client updates:

• Removed the GetAPIKeyBySearchingAllEnvironments method from the mock client and added the GetEnvironmentAPIKey method. (pkg/account/client/mock/client.go) [1] [2]
• Updated the mock storage to include the new GetEnvironmentAPIKey and ListAllEnvironmentAPIKeys methods. (pkg/account/storage/v2/mock/storage.go) [1] [2]
