Feat/onboarding wizard (#2086)

* feat(web): add onboarding wizard for guided bot creation

Implement a full-screen 4-step wizard at /wizard that guides users
through selecting a platform, configuring a bot, choosing an AI engine,
and completing setup. The wizard uses DynamicFormComponent for adapter
and pipeline configuration, embeds BotLogListComponent for real-time
debugging, persists state to localStorage, and integrates with Space
OAuth flow. Also fixes a prompt-editor crash in DynamicFormComponent
when value is undefined.

* feat(wizard): redesign step 0/1 flow, add skip dialog, auto-expand log images

- Step 0: Remove bot name/description fields; auto-derive name from adapter
  label; create disabled bot on confirm; advance to Step 1 automatically
- Step 1: Replace 'Create Bot' with 'Save & Enable Bot'; update adapter
  config and enable bot; disable form fields after saving
- Add skip confirmation AlertDialog with i18n message
- Add LanguageSelector to wizard header
- Move wizard sidebar entry to last position to prevent fallback redirect loop
- Add defaultExpanded prop to BotLogCard; auto-expand entries with images
  in wizard via autoExpandImages prop on BotLogListComponent
- Remove automatic default pipeline creation (write_default_pipeline) from
  backend persistence manager since the wizard now handles pipeline creation
- Update all 4 locale files (en-US, zh-Hans, zh-Hant, ja-JP)

* fix(wizard): hide detailed logs link in wizard, allow re-editing bot config after save

- Add hideDetailedLogsLink prop to BotLogListComponent; pass it in wizard
- Remove isEditing on DynamicFormComponent so form stays editable after save
- Always show save button; label changes to 'Re-save' after first save
- Add resaveBot i18n key to all 4 locale files

* style(wizard): move save button into config card header

* fix(wizard): initialize userInfo/systemInfo so model selector works

The wizard runs outside /home layout, so userInfo was null. This caused
the model-fallback-selector to filter out all Space models, showing an
empty dropdown. Fix by calling initializeUserInfo() and
initializeSystemInfo() before fetching wizard data.

Also:
- Hide log toolbar in wizard via hideToolbar prop on BotLogListComponent
- Add empty state message for bot logs (noLogs i18n key, all 4 locales)

* feat(wizard): redesign AI Engine step with left-right split layout

Before selecting a runner: centered grid of runner cards.
After selecting: left panel shows compact runner list for switching,
right panel shows runner config form with slide-in animations.

Also fix prompt field default: add default value to prompt-editor field
in ai.yaml metadata so the prompt is pre-populated with
'You are a helpful assistant.' instead of being empty.

* feat(pipeline): add default values to ai.yaml runner configs and show_if for n8n auth fields

- Sync default values from default-pipeline-config.json to all runner
  config fields in ai.yaml so wizard forms are pre-populated
- Add show_if conditions to n8n-service-api auth fields so only the
  relevant credentials appear based on selected auth-type
- Fix prompt-editor crash in DynamicFormItemComponent when field.value
  is undefined (Array.isArray guard + fallback)
- Improve wizard Step 2 split layout with fixed column widths,
  independent scroll, ring clipping fix, and mobile responsiveness
- Use key={selected} on DynamicFormComponent to force remount on
  runner switch
- Improve pipeline creation flow: create → fetch defaults → merge AI
  section → update (preserves trigger/safety/output defaults)

* feat(dynamic-form): add systemContext prop with __system.* namespace for show_if conditions

- Add systemContext prop to DynamicFormComponent for injecting external
  variables accessible via __system.* prefix in show_if conditions
- Extract resolveShowIfValue() helper for cleaner field resolution
- Pass { is_wizard: true } from wizard to hide knowledge-bases field
- Remove bot config save toast in wizard (keep inline indicator)

* feat(sidebar): render wizard as standalone item before Home group with fallback redirect fix

* fix(wizard): remove unused setBotDescription to fix lint error
