Review fixes for the CAP compatibility test suggestion:
- A cntr_low rejection is exempt from both the failure hint and the
one-click button: the card never executed the command (the packet's
counter was rejected), so the counter box is the actionable path -
the v3.6.58 rule that a low counter is never retried.
- The INSTALL [for load] advice names the cascade action: the package
row's "Delete All" (a plain delete of a package with related objects
can be refused), in EN and RU.
- The RU LOAD hint quotes the RU button label ("Все 0.0" rather than
the English "Set all 0.0").
- Two orphaned LANG_RU entries from the replaced hint strings removed
(the i18n test only checks the missing direction, so they survived).
Tests: the counter-low exemption, the cascade wording and the button
guard pin. 862 frontend + 842 Python; sw cache simple-v422.
