AssetManager v0.5.3.3

- German terminology standardized from "Auftrag/Aufträge" to "Job/Jobs" throughout software and job pages.
- Dark-mode category initials on the dashboard use a dark foreground on the light placeholder tile.
- Fixed the job-framework generator: unescaped Bash template expressions caused the page JavaScript to stop before event handlers were registered.
- Added a safe "Insert test script" action for PowerShell, CMD, Bash and Python.
- Job framework and test script insertion now trigger an input event and a translated success message.
- All new visible texts are translated in German and English.
