Cleaner Speaking Mode & Precise Audio Sync

🛠 Fixes

• Fixed: system now waits for the final transcription text before handling the last branch — prevents early section processing
• Fixed: “Empty” placeholder now shows properly and adjusts width automatically
• Fixed: corrected recorded section timing - each branch starts exactly at the right moment

✨ New Features

• Removed unused extra buttons to simplify interface
• Dropped text field in Speaking mode — focus stays on voice input, not on blank boxes

  After

• Flexible button width in Speaking section - fits better across layouts
• Changed Star button color from orange to yellow - makes highlights easier to spot

🔄 Improvements

• Layout feels cleaner and more focused during recording and transcription
• More precise sync between spoken sections and map branches
