Add card tab type support for JideTabbedPane

[FoxyBOA]

Summary

FlatLaf supports the "card" tab type for standard JTabbedPane via UIManager.put("TabbedPane.tabType", "card"), but this style was not available for JideTabbedPane. This PR adds card tab rendering directly into FlatJideTabbedPaneUI, bringing feature parity with the standard FlatTabbedPaneUI.

Changes

• Read TabbedPane.tabType, TabbedPane.cardTabSelectionHeight, and TabbedPane.cardTabArc UI defaults in installDefaults()
• Support per-component override via JTabbedPane.tabType client property
• Paint rounded card tab background when cardTabArc > 0
• Paint card tab border frame around the selected tab
• Paint card tab selection stripe at the outer edge of the selected tab
• Paint content separator gap under the selected card tab (consistent with FlatTabbedPaneUI behavior)
• Skip tab separators adjacent to the selected card tab
• Also fixed an instanceof check in paintTabBackground() before casting _closeButtons[tabIndex] to NoFocusButton

How to test

UIManager.put("TabbedPane.tabType", "card");
// or per-component:
tabbedPane.putClientProperty("JTabbedPane.tabType", "card");

All four tab placements (TOP, BOTTOM, LEFT, RIGHT) are supported, both in wrap and scroll tab layouts.
