Hide additional item tooltips (banner patterns, potion effects, etc.) in all panels using modern TooltipDisplay API

[Copilot]

Panel items with rich metadata (banners, potions, spawners, bundles) leaked per-item tooltip lines into menu lore, cluttering the display and making intended text harder to read.

Changes

• PanelItem.java — Replaced the deprecated ItemFlag.HIDE_ADDITIONAL_TOOLTIP with Paper's modern TooltipDisplay data component API. A new hideAdditionalTooltip() helper method uses TooltipDisplay.tooltipDisplay().addHiddenComponents() to hide item-specific tooltip information (banner patterns, potion effects, firework effects, jukebox playable, suspicious stew effects, bundle contents, and map decorations). The method merges with any existing tooltip display set by the non-deprecated ItemFlags (HIDE_ATTRIBUTES, HIDE_DESTROYS, HIDE_PLACED_ON, HIDE_ENCHANTS) to avoid overwriting them. Called at the end of both the constructor and setHead().

• PanelItemTest.java — Updated testSetHead to verify the TooltipDisplay data component is applied via setData() instead of the deprecated HIDE_ADDITIONAL_TOOLTIP flag.

Since all GUI panels go through PanelItem, this fix covers every menu in BentoBox (language selector, settings, admin panels, etc.) without any per-panel changes.

@copilot ItemFlag.HIDE_ADDITIONAL_TOOLTIP is Deprecated and the notes say:
does not exist anymore and will not properly work with individually hidden data components; see io.papermc.paper.datacomponent.item.TooltipDisplay and ItemStack.setData(DataComponentType.Valued, Object)

Is there an alternative approach that isn't deprecated?

Replaced with Paper's modern TooltipDisplay data component API in 7c0e6a9. The new hideAdditionalTooltip() method uses TooltipDisplay.tooltipDisplay().addHiddenComponents() to hide banner patterns, potion effects, firework effects, jukebox playable info, suspicious stew effects, bundle contents, and map decorations. It also merges with any existing tooltip display set by the non-deprecated ItemFlags (HIDE_ATTRIBUTES, etc.) to avoid overwriting them.
