editor: add resize SFX while dragging resize handles

[wass08]

What does this PR do?

Adds a resize sound effect that plays while dragging a node's resize handles.

• Registers a resize SFX in sfx-player.ts — three round-robin variations (resize_0/1/2.mp3) with pitch/pan jitter, reduced volume, and an 80ms minimum gap so a sustained drag reads as texture rather than a machine-gun tone (mirrors the gridSnap approach).
• Adds the sfx:resize event + mapping in sfx-bus.ts.
• Emits sfx:resize from the linear/radial resize drag handler in node-arrow-handles.tsx only when the snapped + clamped value actually changes, so the cue ticks on real size steps (width / length / depth / radius / wall + chimney height) instead of every sub-pixel pointer jitter. Rotation handles keep their existing item-rotate cue.

How to test

1. bun dev and open the editor.
2. Ensure audio is unmuted in the editor's audio settings.
3. Select a node (e.g. an item, column, or wall) and drag one of its resize handles — width/length/depth chevrons, the radial column handle, or the wall/chimney height tracker.
4. Expected: a soft tick steps as the size changes; the cue does not stack into noise on fast drags, and rotation drags still play the rotate cue (not the resize one).

Screenshots / screen recording

N/A — audio change; no visual diff. (Happy to attach a screen recording with sound if useful.)

Checklist

• I've tested this locally with bun dev
• My code follows the existing code style (run bun check to verify)
• I've updated relevant documentation (if applicable)
• This PR targets the main branch

Note

Low Risk
Editor-only audio and a narrow emit guard on the existing resize drag path; no auth, data, or scene persistence changes.

Overview
Adds resize tick audio while dragging linear and radial resize handles (width, length, depth, radius, wall/chimney height trackers), without changing rotation handles.

A new sfx:resize event is registered in the SFX bus and backed by a resize sound in sfx-player — three round-robin clips, quieter volume, pitch/pan jitter, and an 80ms minimum gap (same idea as grid snap) so fast drags sound like stepped texture instead of a steady tone.

In LinearArrow’s resize move handler, the cue fires only when the snapped and clamped dimension value changes, so ticks align with real size steps rather than sub-pixel pointer movement.
