Intl sv-SE formats negatives with U+2212, which the bundled react-pdf Helvetica/Courier fonts cannot render, so a loss printed as a profit. lib/pdf/number-text.ts pdfNumberText maps U+2212 to an ASCII hyphen and prints negative zero unsigned; routed through financial-statement, kassaflodesanalys, reskontra, momsdeklaration, payslip (fmt, the literal Preliminar skatt sign and the calculation formula text) and operational-report templates, with content-stream regression tests. The K2/K3 arsredovisning templates keep main's formatPdfKronor from #2013. Closes #1982

/**

*
|
|
* `Intl.NumberFormat('sv-SE')` and `toLocaleString('sv-SE')` write negatives
|
|
* with U+2212 MINUS SIGN, not the ASCII hyphen-minus. The bundled standard
|
|
* PDF fonts (Helvetica, Courier, Times: WinAnsi encoding) have no glyph for
|
|
* U+2212, so react-pdf emits an unmapped byte and the viewer draws nothing:
|
|
* a loss prints as a profit, a credit note as a charge (issue #1982, first
|
|
* seen on Årets resultat in the årsredovisning PDF).
|
|
*
|
|
* Run every locale-formatted amount through this before it reaches a <Text>
|
|
* that uses a standard font. Embedded TrueType fonts do carry the glyph, but
|
|
* the ASCII hyphen renders identically there, so applying it everywhere is
|
|
* safe.
