Aşama 1: Layout yönetim UI — yeniden adlandırma, silme, context menüsü

- Layout sekme sağ-tıklamasında context menüsü (Yeniden Adlandır / Sil)
- Inline rename: sekme metin-giriş alanına dönüşür, Enter ile commit, ✕ ile iptal
- LayoutDelete: layout ve sahip olduğu tüm entity'leri kaldırır
- LayoutRename: Layout nesnesinin adını yerinde günceller
- LayoutCreate çakışma koruması: mevcut isimler arasında benzersiz ad bulur
- Escape tuşu açık rename/context menüsünü kapatır
