Bytt djuplenkjer frå tilfluktsrom:// til HTTPS App Links

SMS-appar gjenkjenner ikkje eigendefinerte URI-skjema som klikkbare
lenkjer. Brukar no https://tilfluktsrom.naiv.no/shelter/{id} som
opnar appen direkte (Android App Links med autoVerify) eller fell
tilbake til PWA i nettlesaren.

Android: DEEP_LINK_DOMAIN i build.gradle.kts, HTTPS intent-filter,
oppdatert handleDeepLinkIntent og shareShelter med HTTPS-URL.

PWA: assetlinks.json for Android-verifisering, djuplenkjehandtering
i app.ts, base-sti endra frå './' til '/', config.ts for domene.
