Beginner UX: purpose-first Traffic Inspector header (#11283)

Validated on a 3-PR combined board: traffic-inspector-beginner-header suite green within the board's 30/30, typecheck:core + dashboard-typecheck clean, gates within baseline. Purpose-first orientation header for Traffic Inspector, existing inspection UI untouched. Thank you @ignamiranda!

+- **feat(dashboard):** lead Traffic Inspector with a purpose-first header that separates "what happened" from "how it happened", so beginners can read request outcomes without drowning in protocol detail ([#11283](https://github.com/diegosouzapw/OmniRoute/pull/11283))
