feat: Typst-typeset statements in US accounting format

0 Fork 0

The printpdf statements padded columns with spaces in a proportional font
(amounts didn't line up), had no company name, printed negatives as
"-207.68", and put everything on one page (a long statement was silently
cut off past ~70 lines). Now:

- PDFs are typeset by Typst from one template,
  ledger-import/templates/statement.typ. The laid-out statement goes in as
  JSON data (sys.inputs), so account names are never parsed as markup.
  Fonts are bundled (typst-assets: Libertinus Serif), so output doesn't
  depend on the machine and is byte-for-byte deterministic. Statements
  paginate, with the company/title repeated on later pages and "Page n of
  m" plus "Prepared from journal through seq N" in the footer.
- US accounting presentation, decided once in ledger-import::report and
  applied by both PDF and XLSX: tabular figures; "$" on each section's
  first amount and on every subtotal and total, pinned to the column's
  left edge; negatives in parentheses with the closing paren hanging (its
  width reserved on every row, so decimal points align); zero as a dash;
  a single rule above sums (none over an empty section) and a double rule
  under statement totals; amounts never bold, because bold figures are
  wider and would leave the decimal column. XLSX uses Excel's own
  Accounting formats for the same result.
- Cash flow: "Net change in cash" is a subtotal; only "Cash at end of
  period" takes the double rule.
- Core fix: cash_flow walked the chart in HashMap order, so the order of
  working-capital and financing lines could change between runs. Lines
  now follow account code. Test: five owners, twenty runs, always
  3000/3001/3003/3005/3009; fails without the sort.

New dependencies (ledger-import): typst, typst-layout, typst-pdf,
typst-assets (fonts), typst-as-lib (World/font plumbing), serde_json (the
template's data). Removed: printpdf. Release ledger-mcp grows by the
bundled fonts.

Tests: exact template data for a hand-built P&L (like a golden); same
statement renders to identical bytes; 200 rows of Typst markup
characters render literally and span several pages; currency-sign and
rule placement; amount splitting.
