[US-035] Deep linking (Universal Links / App Links)

[leimo2011]

User Story

As a user,
I want links shared from the app to open directly in the app (not browser),
So that the experience is seamless when sharing store profiles or live links.

Acceptance Criteria

• iOS Universal Links configured for liemo.app domain
• Android App Links configured for liemo.app domain
• Store profile URLs (liemo.app/store/{slug}) open store page in app
• Live link redirect URLs handled in-app
• Fallback to web if app not installed

Estimate: 3 SP | Milestone: M4
