chore(android): extend detekt TooManyFunctions exception to @Database

AppDatabase grew its 12th DAO accessor in slice 9 and tripped the
TooManyFunctions rule. Same shape as the @Dao case from slice 5 —
Room types naturally accumulate one method per entity family. Added
"Database" to the ignoreAnnotated list alongside "Dao".
