v1.2.0

• Added a uiStyle client config option to choose the Spell Codex UI. Edit config/nomorespellbooks-client.toml:
  • 0 = default (Tensura style) — the original look.
  • 1 = Minecraft style (book). Any out-of-range value falls back to 0.
• Added a new Minecraft guidebook-style Spell Codex (uiStyle = 1): a procedurally drawn open book (leather cover + parchment page) with framed, clickable tabs, a search field, and paginated rows (6 per page) navigated with page-turn arrows.
• Both UI styles share the same features — Installed / Learned / Learn tabs, search, level +/− steppers, Install / Remove / Learn / Unlearn, and drag-to-reorder — and use the same server-validated actions.
• Default behavior is unchanged: existing setups keep the original UI unless uiStyle is set to 1.
• (1.21.1) Removed the hidden spell_codex Curios slot and the virtual spellbook item. Installed spells are now injected directly into Iron's spell selection (the same approach as the 1.20.1 build), so casting needs no spellbook item or Curios slot at all.
• (1.21.1) Fixed the spell wheel not updating immediately after installing / removing / reordering spells in the Codex.
