add conversation expire config & user query text to dingtalk card (#2147)

Browse Source 
* add conversation expire config

* add user query text to card

* fix(pipeline): move session limit to AI config

* test(pipeline): cover AI session limit config

* refactor(pipeline): merge session expire-time into AI runner stage

Move the session validity duration field out of the standalone
session-limit stage into the runner stage so it actually renders in the
AI tab (the tab only shows the runner stage and the stage matching the
selected runner — any other stage is filtered out). Read path, default
config, metadata description, and tests updated accordingly.
