Two things needed for the new UI to actually reach users.
The rendered nginx.conf served index.html with only ETag/Last-Modified and
no Cache-Control, so browsers applied heuristic caching to it. Confirmed on
archi-dev-box: after rebuilding and recreating the container, :8334 and
/app/bitcoin-ui/ both served the new markup immediately, but the app iframe
in the main UI kept showing the previous UI until a hard refresh.
docker/lnd-ui/nginx.conf has always carried this header, which is why only
bitcoin-ui showed the stale copy. Using "no-cache" (revalidate) rather than
"no-store" keeps the ETag doing its job when nothing has changed.
Validated by mounting the rendered config into a throwaway container from
the built image and running nginx -t. (An earlier attempt to test it inside
the running container was meaningless — conf.d/default.conf is a read-only
bind mount, so the copy failed and nginx -t just re-checked the original.)
The 8 container::bitcoin_ui tests still pass; their assertions cover the
placeholder, the 8332 proxy_pass and the listen directive, none of which
this touches.
BITCOIN_UI_IMAGE was still pinned to 1.7.84-alpha, so a fresh install would
pull a bitcoin-ui from many releases ago regardless of what the OTA ships —
first-boot-containers.sh tries the registry image before building from
source. Bumped to 1.7.119-alpha, matching the current release, and the
image is pushed under that tag.
