Fix two critical session issues in Claude Code IDE

Issue 1: Sessions history not showing in left sidebar
- Converted loadChatHistoryOnLoad IIFE to named loadChatHistory() function
- Added refresh calls in loadSessionMessages() after loading messages
- Added guard to skip refresh if showing "Loading session..." state
- Sidebar now properly shows all active sessions after attachment

Issue 2: New chat session button fails with 'Failed to create session'
- Changed startNewChat() to call loadChatHistory() instead of loadChatView()
- Prevents triggering URL-based attachment logic that was causing confusion
- Sidebar now refreshes correctly without getting stuck in loading state

Also updated cache-bust version to force browser reload.

+# Session Fixes - Scratchpad
+
+## Task Overview
+Fix two critical issues in Claude Code IDE:
+1. Sessions history not showing in left sidebar after attaching to a session
+2. New chat session button fails with 'Failed to create session'
+
+## Environment
+- Server: /home/uroma/obsidian-web-interface/server.js (PID 1736251)
+- Frontend: /home/uroma/obsidian-web-interface/public/claude-ide/
+- Session URL: https://rommark.dev/claude/ide/session/session-1769081956055-str90u48t
+
+## Iteration 1 - Current State
+- Created scratchpad
+- Need to explore codebase structure
+- Need to check server logs for API errors
+- Need to verify session creation endpoint
