fix(tui): clean up stream row density — drop ID, fix newline leak, align margins

ID cluttered rows and caused wrapping on long entries. Body newlines
leaked into stream rendering extra unindented lines. Cursor glyph
shifted selected rows 1 col right of unselected.

Remove ID from all row renderers (detail pane already shows it),
collapse multiline body to first line, cap tags to 2 in stream,
and reserve cursor column on unselected rows for consistent alignment.
