Live translation, pathways, knowledge base, and webhook improvements

Live Translation & Transfers

• Fallback to regular warm transfer if live translation bridge initialization fails - Enhanced merge prompts for warm transfer calls with live translation

Pathways & Routing

• Added pathway version JSON upload functionality - Transfer node extension field now supports variable substitution using {{variable_name}} syntax - Strengthened current year validation in scheduling node

Knowledge Base & Personas

• Fixed inbound persona calls to properly reference configured webhook endpoints - Integrated knowledge base gaps detection with personas

Voice & Audio

• Increased background noise threshold by 20%

Web Widget

• Improved session management after periods of user inactivity

API & Development

• Fixed webhook timeout handling where calls would go silent due to missing BlandStatusCode. Now properly sets status code to 0 on timeout to allow routing logic execution
