feat(ui): dialogue UI hardening and examine result overlay (#174)

Confrontation options use RichTextLabel with italic tags for
first-person voice (D-063). Examine result overlay auto-dismisses
after 5s with confidence-based color tinting. Dismisses when
dialogue opens. D-062 invisible locked options confirmed correct.
