* ui : keep markdown tables inside the chat column on phones
The phone rule made the table wrapper full-bleed with -1rem margins, so the
first and the last column sat under the screen edge. Keep the wrapper inside the
chat column and cap it at its width, so a wide table scrolls in place instead.

* test : show a table-only model answer in the chat message story
Adds a story with an answer that is mostly a table, so the table layout can be
checked at a phone width.

* ui : indent markdown lists by 2rem
1.5rem put the marker too close to the item text.
