The SIE-import mapping table was a fixed layout of 1216px, with 144px
spent on a four-digit source account and the VAT cell's min-w-72
overflowing 32px into Konfidens, so on a laptop content column it
scrolled sideways and read as cramped even after #1684 kept the confirm
button reachable.
- Column budget ~990px: Källkonto w-20, Källnamn w-40 (existing
truncate + tooltip), arrow w-8, Målkonto w-56, VAT w-72 with the
treatment select flex-1/min-w-0 and the rate select shrink-0,
Konfidens w-24, Bekräfta w-28.
- 13px text and px-3 cells, matching the page-level list density.
- Bekräfta is an icon-only button (Check) with a tooltip; the header
keeps the label and gains an InfoTooltip explaining what confirming
does (new chart_of_accounts.vat_treatment_confirm_help, sv + en).
Closes#2125
