On a page with /Rotate 90, 180 or 270, Fill & Sign placed typed and drawn signatures and initials sideways or upside down: their box and their strokes/outlines were laid out along user-space axes, which the page turns, while the click (or fill_sign_add's "at") is a displayed point. Only image signatures were counter-rotated (#485). Both now use the same displayed axes as image signatures (pdfcraft_model::view_matrix_for without its offset): the box's left edge and vertical centre are at the displayed point, a drawn signature's ink points are mapped through the displayed right/up vectors, and a typed signature's normalised outlines are turned back inside a user-space box laid out along the turned page (the shared signature_image::upright_box, now also used by SignatureImage::rect). The appearance is plain geometry, so every viewer shows it upright without relying on a form /Matrix. Unturned pages are unchanged (the mapping is the identity there). typed_signature_shape and fill_sign::{signature_at, typed_signature_at} take the page rotation; fill_sign::place and fill_sign_add pass it. Tests: a kittest-file test places a drawn, typed signature and typed initials on /Rotate 0/90/180/270 pages through fill_sign::place, renders them and checks each displayed ink box is wider than tall, anchored at the point, identical to the unturned page, and that an asymmetric drawn stroke is not mirrored; an automation test does the same for fill_sign_add typed signatures and initials, before and after save/reopen.
