* Add group story support to core library layer
Extend Manager.sendStory() with an optional GroupId parameter and add
SendHelper.sendGroupStoryMessage() for endorsement-aware group story
delivery, laying the groundwork for group story support (task 1 of 4).
The existing My Story code path is unchanged.
* Add --group-id support to SendStoryCommand
Passes an optional GroupId through to Manager.sendStory so stories can
be posted to a group instead of only My Story, and surfaces
GroupNotFoundException / NotAGroupMemberException as user errors.
* Update stubs for 3-parameter sendStory and add empty-recipient guard
Updates DbusManagerImpl and StubManager (in SubscribeCallEventsTest) to
match the new 3-parameter sendStory signature: (String attachment,
boolean allowsReplies, Optional<GroupId> groupId).
Also includes the empty-recipient guard added after Task 1 review to
prevent stories from being sent to groups where the user is the only member.

the pattern from sendGroupMessageInternal
- Add debug logging when recipients are filtered out
- Fix redundant error message prefixing in SendStoryCommand
