Introduce `AddUserToOrganization`, `RemoveAPIKey`, and
`RemoveOrganization` commands to enhance organization
management. Implement validation for user addition and
API key removal. Update GraphQL schema to support new
mutations and add caching for the new events, ensuring
that organizations and their relationships are accurately
represented in the cache.
Adds a new hashed key storage mechanism for API keys in the cache.
Replaces direct mapping to API keys with composite keys based on
organizationId and name. Implements searching of API keys using
hash comparisons for improved security. Updates related tests to
ensure correct functionality and validate the hashing. Also,
adds support for a new dependency `golang.org/x/crypto`.
Adds unit tests for the WebSocket initialization function to validate
behavior with valid, invalid, and absent API keys. Introduces a mock
cache implementation to simulate organization retrieval based on
hashed API keys. Ensures proper context value setting upon
initialization, enhancing test coverage and reliability for API key
handling in WebSocket connections.
