fix: return an array from SpatieTagsEntry/SpatieTagsColumn getState() when state is not a Collection or array

The early-return branch returned the raw state from a method typed `array`,
which threw a `TypeError` for any truthy scalar state. PHPStan 2.2.8 narrows
`mixed` more precisely and surfaced this, failing CI on every branch.
