Sweep every browser gate for English-text matchers; fix the fifth and last

The same defect had surfaced in FOUR gates across previous ticks — a gate keyed on
English prose silently excludes every translated surface, or goes red on a
correctly translated one. Finding a fifth by accident would mean the pattern was
still being discovered rather than eliminated, so this sweeps all 25 gates that
drive a browser instead of waiting for the next one.

9 flagged, 8 benign: CSS class names (.vtl-fab, .stl-panel) and CSS property VALUES
(/paint|layout|strict|content/) are locale-independent by definition.

ONE REAL HIT — check-poster-prints.mjs:131, `/Gadarenes/.test(...)`. That is the
World English Bible's proper noun, so the assertion and the bug were locked
together: it passes today ONLY because point4_passage is still English in all ten
non-English blocks. The day a licensed translation lands it would have gone red on
a CORRECT packet. Now asserts the .p4-passage block by length, the same structural
fix already applied in check-packet-render and check-packet-browser.

Proved on the case the old matcher got wrong: renaming Gadarenes -> gadarenos, as
any translation would, now PASSES where /Gadarenes/ would have failed.
MUTATION-TESTED both directions — a passage truncated to 180 chars FAILS ("looks
truncated: 259 chars"), and the .p4-passage block renamed in the MARKUP FAILS
("no .p4-passage block").

★ ONE MUTATION SILENTLY DID NOT LAND, and it is worth recording. My first attempt
at the second mutation used a count=1 replace, which hit the explanatory COMMENT
rather than the markup — "p4-passage" appears twice in packet-render.js. The gate
"passed" and I nearly recorded a hole in the assertion. The assertion was sound;
the mutation was not. The sweep made the same class of error in the other
direction, flagging check-packet-render for a "Gadarenes" that lives only in a
comment explaining why it was removed.

Five instances found and fixed across five ticks; none remain in live code. The
rule for any new gate: if it matches on user-visible text, resolve the expected
string from the catalog for the page language, or assert on STRUCTURE — a class
hook, a length — instead.
