fix(session-manager): carry mode, claudeSessionId and resumeId into rows (#477)

_loadSessionManagerList() re-projects each unified item into the
history-record shape _buildHistoryItem renders, and dropped these three
fields. The row's own onActivate still read them from the unified item, but
everything built from the record did not: the ⋯ menu's "Resume session"
relaunched a codex row as claude (no mode, no resumeId), a resumed session
lost its conversation id, and Cmd+K rows showed no mode badge. Same class
of bug as the worktree fields the re-projection already carries (#266).
