TE-006: StamdataStore.download(), BriefStore.previewLetter() and
OrgTemplateStore.proefbrief() each ended in raw DOM blob calls jsdom cannot
meaningfully execute, so their success paths were unassertable and
download()'s two-clause guard true-branch was permanently dark.
BLOB_PRESENTER mirrors the SESSION_PORT shape; all three commands go through
it. download()'s branch coverage goes from 40.5% to 67.6%, and
org-template.store.ts gets its first spec at all.
