IAV-1169/ Unify integration config views, guide cards, switches and wizard skeleton
- AddAccountModal: added missing config views for LinkedIn (CM + RH), Twitter, and TikTok; extracted a shared platformGuideSection useMemo rendering animated guide steps + docs button for all dynamic and custom config view cases; fixed dead-code branch that made Facebook/Instagram config views unreachable
- BaseGuideCard: redesigned with unified futuristic style — hover lift + shimmer sweep on step items, pulse glow on step number bubbles, gradient text, shine effect on docs button
- SAV config views (Telegram, WooCommerce, Freshdesk): replaced old flat inline guide sections with BaseGuideCard
- CM config views (LinkedIn, Twitter, TikTok): added hideGuide prop to suppress internal BaseGuideCard when parent already renders a guide
- Switches (LegalNotificationsSection, Legal integration card): unified to green #10B981 (active) / red #EF4444 (inactive)
- LegalNotificationsSection: fixed TextField focus border to use full agent primary color via .MuiOutlinedInput-notchedOutline
- WizardStepSkeleton: added per-step skeleton layouts; submitting state now shows only the animated dots card (skeleton hidden); overlay redesigned with glassmorphism card
- Wizard index: step header (title + subtitle) shows skeleton bars during isInitializing instead of rendering empty text
