Three concat lib tests fail on main after the recent merges

[Domica]

Problem

Three cargo test -p concat --lib tests fail on main. Every PR based on
main is blocked on them.

1. format::tests::zooming_in_reveals_the_fine_buckets_and_never_loses_a_peak

assertion `left == right` failed
  left: 2
 right: 1

The test expects one column to carry the spike; the waveform code counts
two after 2430478 perf(ui): waveforms at unity, scaled by the volume.
Either the test's expectation or the bucket assignment needs updating.

2. i18n::tests::every_shipped_locale_parses_names_itself_and_keys_off_the_inventory

de.json lacks ["Curvature", "Kaleidoscope", "Enhance", "Magnetic timeline",
               "Limited", "Colour range", "full range", ...]
(~200 keys, in every non-en locale)

English gained the strings from the effects expansion, Enhance, magnetic
timeline and Remote work; the other twelve locales have not caught up.
python3 scripts/locales.py --check would have caught this at merge time
but it is not in the CI gate.

3. panes::settings::listen_tests::a_missing_or_bad_half_gets_the_default

assertion `left == right` failed
  left: ("192.168.1.9:", 7420)
 right: ("192.168.1.9", 7420)

The listen-address parser keeps a trailing colon on a missing port; the
test expects the colon stripped.

Impact

Every PR based on main fails Engine tests and lints on one of these
three. Four of mine (#175, #176, #178, #179) are blocked. The fmt half
is fixed by #176; the three tests are not.

Reproduce

cd src
cargo test -p concat --lib zooming_in_reveals_the_fine_buckets
cargo test -p concat --lib every_shipped_locale_parses
cargo test -p concat --lib a_missing_or_bad_half_gets_the_default

All three fail on 041a233.
