feedback5 WU: module type icons get one lower-case file per type (dec-X and dec-x were two names for one file)

The official data spells one DEC X module 'dec-X' (uniequip_003_aglina) and the others 'dec-x' (WAH-Y is the other
mixed-case type id), and the asset plan stored each under its own case: module/dec-X.png and module/dec-x.png. On
Windows / macOS those are one file, so a release zip built there could hold only one of them and a case-sensitive
server (a Linux VPS) would miss the other — the release packager found it ("planned but not staged"). The local file
is now module/{typeIcon in lower case}.png; the upstream names keep their order (the id as spelled, then lower case).

data/assets.json regenerated offline (node tools/fetch-assets.mjs --offline --add-only). JSON diff: modules.dec-X
/assets/module/dec-X.png -> /assets/module/dec-x.png, modules.WAH-Y /assets/module/WAH-Y.png -> /assets/module/wah-y.png,
hash, stats.files 6979 -> 6978, stats.bytes 458334505 -> 458333444; nothing else.

fetch-assets compares its orphans (what --prune deletes) without case: on Windows / macOS module/WAH-Y.png on disk is
the listed module/wah-y.png and must not be deleted (orphanFiles, exported).

Tests: test/assets-diy.test.js (one lower-case file per type, no two manifest URLs differing only in case, orphans).
docs/ASSETS.md: the module icon file name.
