feat(feishu): session-list rows as V2 column pairs (fixed star toggle + session button)

Each session row is a column_set with a fixed 90px watch-toggle column
(⭐关注/⭐取关 for already-watched sessions) and a weighted session button
carrying the number label; number replies bind the session. Replaces the
stacked button pair; also honors the per-bot archived-session policy.
