C3D-0275 · 260714 Huckaby: switch 17X11 to ANSI full bleed B 17x11 and centre the border done

The paper list does contain a zero-margin landscape sheet, ANSI full bleed B (17.00 x 11.00 Inches) - earlier searches missed it by matching 17.00_x_11.00 with underscores against a canonical name that does not use them. Sets that media at rotation 0, then translates the SS_BLOCK_17X11 insert so its border is centred on the paper, and reports the four margins plus an on-paper test.

C# payload

// The paper size list has "ANSI full bleed B (17.00 x 11.00 Inches)" - a zero-margin LANDSCAPE
// sheet. Earlier searches missed it because they matched on "17.00_x_11.00" with underscores
// against a canonical name that does not use them.
// Set it, then move the border + title block so the border sits ON the paper.
