Parity fixtures: re-capture stacks_full, stacks_unhealthy_stop, stacks_install_interrupted for the Apps card layout (R-909)

Reason: a deliberate LAYOUT change, not a translation. Deleted and re-written with
`go test -run TestI18nParity -update-i18n-golden -i18n-golden-only '^stacks_'`.
Measured: each equals its predecessor with exactly the template change applied (div.stack-title-text,
the address span.subdomain-text + title, the div.stack-tags row) — byte-for-byte, 3 of 3; the visible
text is identical. No Hungarian string changed; no other fixture moved.
