v0.258.0: the last four Hungarian things an English household met

R-589 the update badge, R-590 the data-folder backup sentence, R-573 the two channel
banners, R-572 two dead helpers. All four were built in Go, which is why neither the
template parity fixtures nor TestI18nEnglishPages could see them; slice 5's LIVE proof
is what found them.

R-590 is the one that matters most: it is a promise about the customer's files. It
said, in Hungarian and under an already-English folder label, that a drop-zone is
temporary and unbacked. The test now asserts the CONSEQUENCE in both languages — and
that the two languages do not produce the same string, which would mean the English
fell back.

R-572 is not what its row said. The row claimed a template renders "vasárnap" on an
English page; measured, NO template and no Go file called pruneLabel or
nextPruneLabel. They were dead func-map entries returning Hungarian, so they are
deleted rather than translated — translating dead code would add machinery with no
reader and a test pinning a fiction. Deletion is fail-loud and that was proven: a
template naming the removed function panics loadTemplates at startup.

Five red-proofs. One of them says something about the gate rather than the code: the
Go-parity gate does not measure localeFuncs keys against the base capture, so the
citation to TestLocaleFuncsHungarianBundleMatchesFuncMap is what carries them — the
test was extended to make that citation true.

MinAgent: 0.131.0 (unchanged). Hungarian byte-identical.
