Updated itemIcon.ts mobile touch behavior

[Milky-way-Galaxy]

Updates item icon controls to work better on mobile/touch devices.

Problem:

• Desktop users can hover item icons to see the item/fluid name.
• On mobile, hover is not available.
• Long-press can trigger context menu / usage behavior instead of showing the tooltip.

Updated behavior:

• Desktop hover: show tooltip/name
• Desktop left click: production recipe
• Desktop right click: usage recipe
• Mobile tap: production recipe
• Mobile double tap: usage recipe
• Mobile hold: tooltip/name

This makes the calculator more usable on Android/mobile browsers while keeping the original desktop behavior.

This should work on mobile much more consistently if no one accept this I'm gonna use the local version
