Force-override Swing foreground colors via UIManager user-defaults layer

Symptom: With dark mode enabled the inner Swing content area now had dark
panels (good) but tab labels, table cells, status-bar labels and button
text were rendering nearly black-on-dark (bad).

Root cause: UIManager.getLookAndFeelDefaults() lookups for FlatLaf's
component foreground keys still resolve to Metal-era dark values after the
JIDE install + FlatLaf re-apply, because some FlatLaf keys are derived /
LazyValue and recompute against state that JIDE seeded.

Fix: After the bulk FlatLaf-defaults copy, explicitly UIManager.put the
foreground / background / selection / disabled / border colors for every
standard Swing component family.  UIManager.put writes to the user-defaults
layer that takes precedence over the LAF defaults, so these overrides win
regardless of what JIDE or derived-value resolution produces.

Also bump the JavaFX dark stylesheet text colour from #d6d6d6 to #ececec so
labels read closer to white on the dark panels.
