Restores "Counts whole years, months or days between two dates." and
appends the units, in the multi-line form rustfmt gives a long entry.
Drops the 256-argument test case: the parser already refuses more than
255 arguments, so it never reached the entry check. (993c108's message
says entry "also refuses" them; it already did.)

Inside DATEDIF( the hint showed only the signature, so the values unit
takes weren't visible while typing it (#363). The hint now adds the
function's description under the signature, wrapped to the hint's
width, the same text the autocomplete list shows (translated where a
Spanish entry exists).

FnSpec::accepts holds the arity check (including Excel's 255-argument
limit) that functions::call and the entry check both use, so entry also
refuses 256 arguments to a variadic function. The evaluator's own check
in calc is unchanged.

A save without a recent user gesture (e.g. over the control channel) is refused with SecurityError and would otherwise fail silently.

XLSX headerFooter kept only oddHeader/oddFooter: a workbook whose header is on a
different first page (differentFirst + firstHeader) or on even pages showed no
header, and saving dropped it. The model now keeps the first/even headers and
footers and the differentFirst / differentOddEven / scaleWithDoc / alignWithMargins
flags; XLSX reads and writes them; the PDF and the Page Layout view use the right
pair per page; in-place editing edits the page's own pair, and the Header & Footer
tab has Different First Page and Different Odd & Even Pages. pageLayout.headerFooter
takes the variants and a page: odd|even|first for one-section edits.
Insert › Header & Footer now switches to Page Layout view and edits the first
page's centre header, as in Excel, instead of opening the codes dialog.

On macOS the UI font (SF) has no Hebrew and no Hebrew fallback face was
found, while cells in Arial drew it: the formula bar showed boxes. The
interface families now carry the cell face ahead of the script fallbacks,
and the macOS Hebrew candidates include ArialHB.ttc / SFHebrew.ttf /
LucidaGrande.ttc.

Text boxes ignored a:rPr (size, bold, italic, typeface, fill, outline),
a:pPr algn, a:bodyPr anchor and spPr/a:ln/a:noFill. They are now read into
Shape::format, drawn on screen and in PDF, and written back.

Re-protecting a password-protected sheet would drop its hash and let a
plain Unprotect succeed; it is now refused. The sheet tab menu offers
Unprotect Sheet on a protected sheet, like the ribbon.

Since #209, printing from the UI hands the print PDF to Services::print, which only
the web build set: on the desktop, Ctrl+P, More › Print, the macOS menu and the
Backstage Print button produced the PDF and dropped it. The desktop app now writes
it to the temporary folder and opens it in the system PDF viewer, whose Print
reaches the printer dialog.
Save As has a Save as type chooser (xlsx, csv, html, pdf); file.save and
file.saveAs with a .pdf path write a PDF of the sheet (they wrote XLSX bytes into
the .pdf and made it the workbook's file). The desktop save picker honours the
suggested type instead of always proposing .xlsx. The macOS Properties item opens
File › Info instead of running file.properties with no fields.

Sheet protection stored an internal FNV hash that was never written to
XLSX, and an Excel sheet password was dropped on import, so imported
protected sheets could be unprotected without it. Protect Sheet now
stores a salted SHA-512 hash (spin count 100000) via PasswordHash; the
XLSX sheetProtection password (iterated or legacy) is read and written,
and Unprotect Sheet really verifies it. Hashes from older GridCraft JSON
workbooks are still read and verified.
