bokftui: Huvudbok/Verifikationslista views, Räkenskapsår screen, ^Enter/^Xv0.1.27

The report menu gains Kapitas-style Huvudbok and Verifikationslista
tables. "Byt räkenskapsår" is now "Räkenskapsår": the list shows
öppen/stängd and ^A closes or reopens the highlighted year (via the new
fiscal_year.reopen). Menus remember the selection, Mallar opens straight
into the list (Enter edit, ^N new, d arkivera), report tables get column
rules and aligned sums, and text_view clears stale lines.

Footer hints write control keys as ^N/^A/^C/^R/^X, ^Enter saves or posts
a form and ^X clears the focused row (F9 still works as a fallback).
