fix(dashboard): route the Adapta tutorial CTA through the branded shortener

The Adapta tutorial modal's CTA linked straight to agent.adapta.one, so those
clicks never reached our metrics. Points the href at
https://link.omniroute.online/adapta (the `adapta` slug on our own shortener)
while keeping the visible link text as the real domain, so users still see
where they are going.

Completes the shortener rollout started in #11196 — that PR created the
`adapta` slug but did not wire this callsite.

Provider baseUrl configs that also mention agent.adapta.one are API endpoints
and are deliberately untouched.
