fix: spec-swap crash and unanchored bind config without Ascension API

- TalentGroupChanged: fall back to GetActiveTalentGroup() (or 1) when
  SpecializationUtil is unavailable, so self.talentGroup is never nil
  (specswap concat crash, pri/sectalent misfiltering)
- ShowWithSpellBook: anchor to UIParent center when
  AscensionSpellbookFrame is missing instead of showing an
  unanchored frame
