R-225/R-227/R-228 Parts 2-4: unknown is not zero, the gateway speaks Hungarian, the set-aside is visible

R-225 — an unread store said '0 pillanatkép / 0 / 50 GB' above a card stating
it held backups under another key. An SFTP listing found snapshot f3d9cd67 and
12 535 KB really there; snapshot_count and repo_size_bytes were simply ABSENT
and the zero value spoke for them. StatsKnown is now NAMED, for the same reason
OffsiteInventory.Empty is: zero is what an unread store and an empty one both
look like, and on the wire 'absent' and '0' are the same bytes. The fill bar
renders only when the fill is known — a 0%-wide bar is a picture of emptiness,
and a picture is a claim. A measured zero still says zero.

R-227 — WHICH LAYER ANSWERS: traefik, and this repo generates its config. But
traefik v3 serves no static files, so a branded proxy page needs a new always-up
container for every 502 on the box — out of proportion, and scoped in the report
rather than built. Shipped instead: the unlock posts via fetch and answers a
gateway failure in Hungarian without leaving the page. Progressive enhancement —
with no JS the plain POST is unchanged and still shows the proxy's error, which
the report says plainly rather than implying otherwise.

R-228 — the set-aside history was recorded in orphaned_renamed_to and read by
nobody: a census found zero references in any template or handler, while 12 535
KB sat at that path. It is surfaced as two facts and stops. It does NOT promise
the history can be reopened, because it cannot be by anyone today (R-199's
inventory is unbuilt) — and the set-aside CONFIRMATION copy was corrected for
the same reason: 'a helyreállítási kód nélkül többé nem lesznek megnyithatók'
implied that WITH the code they could be. The field's own comment called it
'recovery-code-recoverable', which was the same over-promise in the code.

Tests: scenarios F, G, H as render tests per branch of each gate. Red-proofs,
each demonstrated failing then restored: remove the StatsKnown guards (F,
'R-225 RETURNED: an unread store reports a snapshot COUNT of zero'), delete the
set-aside block (H). The F assertion on the fill bar is scoped to the bar's own
container — a bare width:0% search matched unrelated elements and would have
passed for the wrong reason.

28 packages ok, vet clean, all controller gates OK (the emoji gate caught a
warning sign in a template comment).
