fix: keep queued system event authority structured

Keep queued system-event owner downgrades as structured runtime metadata while rendering the model-visible prompt as plain `System:` lines. This preserves least-privilege wakeups for webhook/node/exec/cron/reaction/hook producers, keeps legacy `trusted: false` compatibility for installed plugins and older hosts, and updates representative gateway, agent, cron, plugin, and OpenGrep coverage.

 ### Fixes

 - Control UI/WebChat: focus the composer when users click the visible input chrome and restore larger, labeled desktop composer controls while preserving compact mobile taps. Fixes #45656. Thanks @BunsDev.
+- System events: keep owner downgrades in structured metadata while rendering queued prompt text as plain `System:` lines, preserving least-privilege wakeups without prompt-visible trust labels. (#82067)
 - Memory search: stop using chokidar write-stability polling for memory and QMD watchers so large Markdown extraPath trees no longer build up regular file descriptors; changed files now settle through the existing debounced sync queue. Fixes #77327 and #78224. (#81802) Thanks @frankekn, @loyur, and @JanPlessow.
