`GetTrainerServiceInfo` answered nil for a rankless service's subText. In 1.12.1 the subText is the Spell record's NameSubtext (`0x4d8b50`, read at `0x4d8b84`), the empty string for a spell with no rank; only a service with no Spell record answers nil (`0x4d8b58`). The resolver now keeps an empty rank as `""` and the binding pushes None as nil. Tests cover both rows and the install-backed Apprentice Blacksmith trainer. Supersedes #1935.
