Fix/frontend optimizations (#2088)

* 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
