fix(panels): wire DiseaseOutbreaksPanel and SocialVelocityPanel into layout (#2389)

Both panels were added as components in #2383 but never registered:
- panels.ts: missing 'disease-outbreaks' and 'social-velocity' entries in
  FULL_PANELS so they never appeared in the panel grid
- panel-layout.ts: missing createPanel() calls and imports so the components
  were never instantiated (data-loader's this.ctx.panels lookups returned undefined)
