chore: Add activity message for conversation resolutions by Captain (#11492)

Currently, when Captain resolves a conversation, the same activity
message used for auto-resolution is shown. This has caused confusion for
users.
With this change, a distinct activity message will be displayed
specifically for resolutions performed by Captain, improving clarity.
