Add API client and types; rename Android package
Switch API usage to a central axios client and app.rocksky xrpc
endpoints. Add many API modules (dropbox, googledrive, graph,
apikeys, beta, likes, shouts, etc.) and corresponding TypeScript
types (Album, Artist, Track, Profile, Scrobble, ApiKey, etc.). Update
hooks and UI to use new response fields (createdAt, albumArt,
albumUri, etc.). Add eas.json and EAS projectId; update Gradle/Kotlin
package and applicationId to app.rocksky.
