feat: clearer import-probe wording, tooltips, translatable titles (v3.6.43)

The probe's checkbox described the mechanism ('Rewrite the CAP's import
versions before the load'); it now reads 'Enable import probe' (purpose
first) with the mechanism in a tooltip, and the field carries two short
hint lines: what the card checks while loading, and the workflow (Set all
0.0 first; if the LOAD passes the list was the cause, then restore one
line at a time to find the package/version the card lacks).

Static tooltips are translatable now via data-l10n-title (handled by
translatePage, checked against LANG_RU by html.test.js together with
data-l10n); the help's RAM-install section documents the two-step
workflow (EN/RU).
