T9.1 - CR-008: the export, finally walked through

Every required field verified present under the Micron configuration: P6
Activity id and description, Priority, the Building/Floor/Sector location
row, Scope & Work, Material List, Constraints with their status carried by
WORDS (a black-and-white print keeps its meaning), Quality & Hold Points, and
the Drawings & Attachments index with per-file descriptions (T7.7's columns).

What must be absent, absent: the Micron samples now carry
fields:{costCode:false, acumaticaTask:false} - CR-002's two removals,
expressed as the toggles CLAUDE.md requires, in the creator sample AND the
wizard sample - so ACU Cost Code and Acumatica Task appear nowhere on the
Micron export while the columns, model and recorded values stay. CR-006-
suppressed sections (assets, kitting) are absent, as pinned since T5.7.

Tablet legibility, three real defects fixed:
- a bare `table { min-width:520px }` in the narrow-screen media block reached
  the EXPORT tables too, dragging the whole document to 520px on a 390px
  screen; scoped to .table-wrap (the form's scroll containers), because the
  export must FIT a tablet, not scroll
- export tables now table-layout:fixed with overflow-wrap:anywhere
- at <=768px the doc sheds its 52/56px desk padding and neutralises the
  inline column widths (the one legitimate !important: outranking an inline
  style is its job)

RAISED, NOT DECIDED (the task says propose, do not assume) - merge versus
list for attachments: RECOMMEND MERGING image attachments into the printed
document (already done - they print inline as the sheet itself) and LISTING
PDFs as named, described links rather than merging them. Merging PDFs
server-side needs a PDF library dependency and re-renders every export for a
need the meeting expressed as "hand someone exactly the sheet" - which the
5MB single-sheet uploads plus inline images already serve. If merged-PDF
output is wanted anyway, it is a bounded server task - needs Nick.

Verification (each probe run alone): NEW tests/export_check.py 17/17.
Regressions: form_structure_check 50/51 (the standing F6 height question,
BL-022), sections_check 95/95.

Items: CR-008 (CR-002 field toggles applied to the samples)

 **Three probes were re-pointed at `T7.1`.** `sections_check.py` 5b drove the live
 cross-frame toggle hand-off, which no longer exists; it now pins the surviving path and
 the fact that an UNSAVED toggle correctly does not travel - a behaviour change, recorded
