Add muted state to Vue nodes (#5770)

## Summary

Added mute state support to Vue nodes with visual feedback and keyboard
shortcut functionality.

## Changes

- **What**: Implemented mute state (mode 2) for Vue nodes with opacity
styling and `Ctrl+M` hotkey support

## Review Focus

Visual consistency between bypass and mute states, and keyboard shortcut
conflict detection with existing hotkeys.

## Test Coverage

- Single node mute/unmute with `Ctrl+M` hotkey
- Multi-selection mute/unmute operations
- Visual state verification with opacity changes

## Related

- #5715
