Remove hardcoded Color.BLACK foreground on JideTabbedPanes

ControllerPanel.getTabbedPane() and NowPlayingPanel.getTabbedPane() each
called setForeground(Color.BLACK) on their JideTabbedPane instances.

Color.BLACK is a plain java.awt.Color, not a ColorUIResource, so it is
never replaced by LookAndFeel.installColorsAndFont() on subsequent UI
installs - it permanently pins the tab labels to black regardless of any
JIDE or FlatLaf defaults the theme manager sets.  In dark mode this leaves
the tab labels black-on-dark and unreadable.

Drop the explicit foreground calls so the LAF (JideTabbedPaneUI reading
JideTabbedPane.foreground / .unselectedTabTextForeground /
.selectedTabTextForeground / .activeTabTextForeground) drives the colour
in both light and dark modes.
