feat: add native app deep links

[devin-ai-integration]

Summary

Adds verified-link handling for https://app.cal.com and https://app.cal.eu URLs that already have native Companion views:

/bookings[/<filter>]                 → bookings tab
/bookings/<filter>?uid=<uid>         → booking detail
/booking/<uid>                       → booking detail
/event-types[/<numeric-id>]          → event types list/detail
/availability[/<numeric-id>]         → availability list/detail
/more                                → more tab

Unsupported links—including username pages and web-only views—remain unchanged. Explicit app links bypass the configured default landing-page redirect so the requested destination wins.

Configures iOS associated domains and Android verified HTTPS intent filters. Host constants live in a pure module so deep-link resolution and Jest coverage do not import React Native runtime dependencies. Domain verification is provided by https://github.com/calcom/cal/pull/4598.

Fixes ENG-1756.

Validation:

• Full repository lint, React Compiler lint, and Cal hostname policy check
• Mobile TypeScript typecheck
• Expo public config generation
• 26 targeted Jest assertions for supported/unsupported links and landing-page behavior
