* fix(web): auto-redirect to wizard on first visit and change sidebar icons to blue * refactor(wizard): use backend metadata table instead of localStorage for wizard completion state - Add wizard_completed field to system info API (read from metadata table) - Add POST /api/v1/system/wizard/completed endpoint to mark wizard done - Frontend home layout checks systemInfo.wizard_completed for auto-redirect - Wizard calls markWizardCompleted API on skip/finish - Ensures consistent behavior across all browsers on the same instance * fix(wizard): update systemInfo in memory before navigation to prevent redirect loop * fix(monitoring): prevent horizontal overflow and unify empty state styles * fix(wizard): use Object.assign for systemInfo and await wizard completion API - Replace systemInfo reassignment with Object.assign in all 3 locations to preserve object identity across module imports - Await markWizardCompleted() POST in wizard skip/finish handlers instead of fire-and-forget to ensure backend persistence - Always re-fetch systemInfo in home layout to get latest wizard_completed state from backend * fix(wizard): prevent redirect loop by blocking navigation on failed status save - Refactor wizard_completed (boolean) to wizard_status (string: none/skipped/completed) - Remove ALL localStorage usage from wizard page (form state persistence) - Replace AlertDialogAction with Button so skip dialog stays open during POST - Add loading spinners for skip and complete actions - If POST fails, show error toast and keep dialog/button active for retry - If POST succeeds, update in-memory state and navigate * fix(wizard): fix row[0].value bug causing GET /info to always return wizard_status=none conn.execute(select(Entity)) returns Row with raw column values, not ORM entities. row[0] is the key column (a string), so row[0].value raises AttributeError which was silently swallowed by except-pass, making the GET endpoint always return wizard_status=none regardless of DB state. * fix(wizard): replace AlertDialog with Dialog for skip confirmation to remove slide animation * chore: optimize toast in wizard * fix(wizard): set default token value for Telegram adapter and initialize adapter config in wizard * feat(web): move webhook URL to dynamic form system, add market category filter, fix layout overflow - Add 'webhook-url' dynamic form field type rendered as read-only input with copy button, defined in adapter YAML specs instead of hardcoded in BotForm. Supports show_if conditions for optional-webhook adapters. - Remove hardcoded webhook display logic from BotForm.tsx, pass webhook URLs via systemContext to DynamicFormComponent. - Fetch webhook URLs after bot creation in wizard and pass to Step 1. - Support ?category= query param on /home/market page for filtering by component type (mirrors langbot-space behavior). - Link 'install knowledge engine' hint to /home/market?category=KnowledgeEngine. - Fix SidebarInset missing min-w-0 causing content overflow when sidebar is expanded. - Add vertical divider between plugin detail config and readme panels. - Fix infinite re-render loop in DynamicFormComponent by memoizing editableItems array. * fix: lint * fix(web): change systemInfo to const to satisfy prefer-const lint rule * fix: update adapter descriptions for clarity and usage requirements
