The t() calls on the Features tab, CRM settings tab, contract editor,
and settings nav carried English fallbacks but the keys were absent from
both locale files, so DE rendered English. Add ~67 keys to en.json +
de.json (DE native): the full contracts.editor.* subtree (whole page was
English), settings.features.{contracts,crmDevelopment,hoursLogging}.*,
crmSettings contracts/dashboard-overview/ToS labels, and two settings
nav titles. Also drop a dead duplicate bills.field.sourceQuote key in de.
