Mobile: fix /playlists/:id deep link routing

[dylanjeffers]

What’s going on

On mobile, the deep-link handler was treating opaque playlist ID URLs like /playlists/:id as profile links. It navigated to the Profile screen with id set to the playlist id, which leaves the profile page stuck showing its skeleton.

Fix

• Route /playlists/:id to the Collection screen with { id }.
• Extracted the deeplink path parsing into a small utility so it can be unit-tested.

Tests

• Added a focused Jest test covering /users/:id → Profile and /playlists/:id → Collection.
  • Run with: npx jest -c packages/mobile/jest.deeplink.config.js
