Add Cockpit process instance restart

[hauptmedia]

Summary

• add a process-definition Restart tab for completed historic process instances
• wire Camunda 7 restart and restart-async REST endpoints
• support default start, start-before/activity, start-after/activity, start-transition, selected historic instances, async batch, initial variables, business-key and listener/IO options
• add scoped process-page styles, translations, state signal, and tests

Verification

• node -e "JSON.parse(require('fs').readFileSync('public/locales/en-US/translation.json','utf8')); JSON.parse(require('fs').readFileSync('public/locales/de-DE/translation.json','utf8')); console.log('translations ok')"
• npx eslint src/api/resources/process_definition.js src/api/resources/process_definition.test.js src/pages/Processes.jsx src/pages/Processes.test.jsx src/state.js src/state.test.js
• npx vitest run src/api/resources/process_definition.test.js src/pages/Processes.test.jsx src/state.test.js
• npx vitest run
• npm run build
• Browser smoke: /processes/proc:1/restart reaches the login boundary without console errors; authenticated restart workflow requires a running backend accepting the dev login

Reference

• Camunda 7.24 Cockpit Process Instance Restart
• Camunda 7.24 REST POST /process-definition/{id}/restart and POST /process-definition/{id}/restart-async
