fix: post-merge type and test fixes

Library.vue: use Song type from store so SongCard's strict platform
union accepts the data (was platform: string, broke after merge tightened
SongCard prop type).

database.test.ts: switch toEqual -> toMatchObject so getBotInstances()
returning extra profile_* schema columns no longer fails the assertion.
