Re-apply FlatLaf defaults after JIDE install + strengthen FX borders

Browse Source 
Symptom: With dark mode enabled, the Swing main window's spectrum chrome and
menu bar were dark (FlatLaf) but tables, tabbed panes and the inner content
area were light/Metal coloured.

Root cause: LookAndFeelFactory.installJideExtension installs JIDE's
Metal-flavored UI defaults (VsnetMetalUtils etc.) into the live UIDefaults
table, overwriting FlatLaf's standard component colors and fonts for keys
like Table.background, TabbedPane.foreground, Panel.background.

Fix: After the JIDE install, walk a fresh FlatLaf UIDefaults table and put
every key back into the active defaults, skipping anything Jide-prefixed.
JIDE's UI delegate registrations live under Jide* keys that FlatLaf does
not define, so they survive untouched while the standard Swing color and
font keys are restored to their dark equivalents.

Also strengthen the JavaFX dark stylesheet: explicit borders on text fields,
tables, titled panes, split-pane dividers and separators so components have
more defining outlines in dark mode.
