docs: Clarify "Actor Standby mode" page title (#2631)

Updated the page title from "Standby mode" to "Actor Standby mode" for
better clarity and consistency with documentation naming conventions.

- Changed frontmatter title to explicitly reference "Actor Standby mode"
instead of the generic "Standby mode"
- Improves discoverability and makes the feature's context immediately
clear to readers

+:::tip Scoped tokens
 You can use [scoped tokens](/platform/integrations/api#limited-permissions) to send standby requests. This is useful for allowing third-party services to interact with your Actor without granting access to your entire account.
 
 However, [restricting what an Actor can access](/platform/integrations/api#restricted-access-restrict-what-actors-can-access-using-the-scope-of-this-actor) using a scoped token is not supported when running in Standby mode.
