[mael-chouteau]

Summary

• French translations with an apostrophe were printed inside single-quoted JavaScript strings ('<?php print __('...'); ?>'), which ends the string and skips the rest of the page script.
• On the device edit page that prevents the "Contacting Device" header from filling even when SNMP works; the same pattern affects device templates, aggregate graphs, the scheduler month selector, CDEF / data source profile dialogs, device rules, and package key prompts.
• Embed those strings with json_encode(), matching support.php, so the apostrophe is string data. __esc() would HTML-encode it and show ' in dialog titles / .text() labels.

Fixes #8555

Test plan

• Set UI language to French
• Edit an SNMP device and confirm the header shows sysDescr / uptime / contact instead of spinning on "Dispositif de contact"
• Browser console has no unterminated-string error on that page
• Spot-check device template delete dialog title, aggregate graph show/hide item details toggle, and scheduler month multiselect placeholder
