FIX: Resolve symlink double-click behavior in file manager

Root cause: Duplicate handleFileOpen function definitions caused symlinks
to be treated as regular files instead of navigating to their targets.

Problem:
- Line 575: Correct implementation with symlink handling
- Line 1401: Incorrect duplicate that overrode the correct function
- Double-clicking symlinks opened them as files instead of following links

Solution:
- Removed duplicate handleFileOpen function (lines 1401-1436)
- Preserved correct implementation with symlink navigation logic
- Added recordRecentFile call for consistency

Now symlinks properly:
- Navigate to target directories when they point to folders
- Open target files when they point to files
- Use identifySSHSymlink backend API for resolution
