Conflicts resolved onto main's newer shape, and the PR's policy applied to
every alloc_id/add_media/new_slide call site main has grown since: commands
answer bad(cmd, NO_ID_SPACE) (slide.reuse, insert.zoom, SmartArt, photo
album, review.accept, handout/notes masters, master placeholders,
background/artistic/compress pictures, transition sound, ink to shape,
paste special, file.new templates); reid/bring_media/renumber/regenerate
and compare::adopt/accept are fallible; outline import keeps what fit.
Tests use expect() on the now-Option results.

alloc_id bumped next_id with saturating_add: a presentation whose
next_id reached u32::MAX (a hostile file can arrive that way;
fix_next_id imports it) handed out that same id to every new slide,
shape, layout and media - duplicate ids, ambiguous references, silent
corruption on every later insert.
alloc_id now returns Option<u32> via checked_add, and every caller
refuses: the engine's insert/duplicate/media/layout commands answer
with a clear error naming the command, paste and duplicate re-id
helpers propagate it, media addition is fallible, and a fresh slide is
Option. The pptx export's synthesized blank layout is guarded the same
way. Loading keeps such a deck viewable: repair re-ids duplicate
slides while it can, and a duplicate it cannot re-id stays as it is -
growth is refused, and only that duplicate keeps its ambiguous id.
Renumbering the loaded graph was rejected: it needs the
cross-document reference remapping that issue #406 tracks.
Tests: model exhaustion (alloc_id None, fresh media refused, a new
slide refused), engine (slide.new, shape.insert, slide.duplicate and
edit.duplicate all refuse; the document holds no duplicate ids),
format repair (an unre-id-able duplicate stays visible).
