SpreadsheetView: keep bullets as single cells with text-wrap

Revert row expansion — multi-line bullet cells stay as single cells
with \n and text-wrap (tb='2'). This way the text reflows when the
user resizes the column, like normal Excel behavior.

Row height auto-scales by line count (24px * lines).
Vertical alignment: top (vt=0) for multi-line cells.
Removed leading-space indentation hack (didn't work reliably).
