docs(assets): codify the authored-footprint rule (araminta ruling, PR #214)

footprint_tiles is an authored value, never derived from normalized
mesh geometry — [1,1] defaults only for plausibly-single-tile classes;
ordinarily-multi-tile classes require an explicitly stated footprint at
promotion. Her exact wording in furniture-props.md §3; conventions.md
§4 gains the authored-not-derived sentence pointing at the full rule
(and a pre-existing 'Single Sunday-tile' typo fixed in passing). The
[1,1] values shipped for the four promoted items stand as ruled.
