fix Vue node opacity conditions (user node opacity, bypass state, muted state) (#6022)

## Summary

Fixed Vue node opacity calculation to properly combine global opacity
setting with muted/bypassed state opacity.

**Root Cause**: When global opacity setting was added as inline style
(481aa8252), it began overriding CSS `opacity-50` classes due to higher
specificity.

**Solution**: Modified `nodeOpacity` computed property to calculate
effective opacity as `globalOpacity * 0.5` for muted/bypassed states,
removing conflicting CSS classes.

## Changes

- **What**: Fixed [CSS specificity
conflict](https://developer.mozilla.org/en-US/docs/Web/CSS/Specificity)
where inline `opacity` style overrode `opacity-50` classes for
muted/bypassed nodes
- **Breaking**: None - restores intended opacity behavior

## Review Focus

Multiplicative opacity calculation ensuring muted/bypassed nodes apply
0.5 opacity on top of global opacity setting rather than being
overridden by it.
