* fix(sie): add ?encoding=cp437 option for legacy bookkeeping software
SIE spec mandates CP437 (#FORMAT PC8) but accounted generates UTF-8.
Most modern cloud tools (Fortnox, Bokio) accept UTF-8 fine, so UTF-8
remains the default. Pass ?encoding=cp437 to get a properly encoded
CP437 binary with #FORMAT PC8 in the header, required by desktop
software such as Visma Administration and BL Administration.
Removes the spurious #FORMAT PC8 tag from the default UTF-8 output
since declaring CP437 while serving UTF-8 caused mojibake on import.

* fix(sie): wrap Uint8Array in Buffer.from so NextResponse accepts it
Uint8Array is not directly assignable to BodyInit in the Next.js
NextResponse constructor — wrapping with Buffer.from() satisfies the
type without changing the byte content.
