feat(access-control): add ALLOWED_INTEGRATIONS env var for self-hosted block restrictions (#3238)

* feat(access-control): add ALLOWED_INTEGRATIONS env var for self-hosted block restrictions

* fix(tests): add getAllowedIntegrationsFromEnv mock to agent-handler tests

* fix(access-control): add auth to allowlist endpoint, fix loading state race, use accurate error message

* fix(access-control): remove auth from allowed-integrations endpoint to match models endpoint pattern

* fix(access-control): normalize blockType to lowercase before env allowlist check

* fix(access-control): expose merged allowedIntegrations on config to prevent bypass via direct access

* consolidate merging of allowed blocks so all callers have it by default

* normalize to lower case

* added tests

* added tests, normalize to lower case

* added safety incase userId is missing

* fix failing tests
