Replace the checkbox + native <select> reassign pattern in CommentThread
with an always-visible InlineEntitySelector (matching the new issue dialog).
The selector defaults to the current assignee and only triggers reassignment
on comment submit if the user changed the selection.
- Remove ReassignOption interface, use InlineEntityOption from InlineEntitySelector
- Add currentAssigneeValue prop to track issue's current assignee
- Remove canReassignFromComment gate so selector is always visible
- Position selector to the left of the Comment button
