The show command's NoteDetail and MrNoteDetail structs were missing
gitlab_id, making individual notes unaddressable in robot mode output.
This was inconsistent with the notes list command which already exposed
gitlab_id. Without an identifier, agents consuming show output could
not construct GitLab web URLs or reference specific notes for follow-up
operations via glab.
Added gitlab_id to:
- NoteDetail / NoteDetailJson (issue discussions)
- MrNoteDetail / MrNoteDetailJson (MR discussions)
- Both SQL queries (shifted column indices accordingly)
- Both From<&T> conversion impls
Deliberately scoped to show command only — me/timeline/trace structs
were evaluated and intentionally left unchanged because they serve
different consumption patterns where note-level identity is not needed.
