Closes#67
Add opt-in Feedback Hub widget integrated into the Settings Logs card. Routes through a Rust command to bypass CORS and centralize privacy audit. First submission triggers a one-time consent dialog; three opt-in checkboxes (context, logs, identify with Maximus account) all unchecked by default. Wording and payload follow the cross-app conventions in la-compagnie-maximus/docs/feedback-hub-ops.md.
