chore(plating): de-dash shipped code + intake-neutral customer emails

Replace em-dashes and en-dashes with hyphens across 789 shipped source
files (py/xml/js/scss) so the delivered module reads as human-written;
em-dashes had become a recognizable AI-generated tell. Internal .md dev
notes are excluded. The WO-sticker mojibake strippers keep their dash
search targets (now written — / –). No logic changes: comments
and display strings only; validated with py_compile + lxml parse.

Rewrite the 7 customer notification emails to be intake-neutral
(ship-in / drop-off / pickup) and repair-aware, and fix the Shipped
email documents line (packing slip vs bill of lading; certificate only
when issued). Subjects use a hyphen separator.
