feat(ai-chat): onboarding iframe styles + strings

abose · abose · commit c3201cc6d17c · 2026-04-27T21:58:24.000+05:30
Companion to the phoenix-pro onboarding iframe wiring.

* Extn-AIChatPanel.less:
  - .ai-tab-container gains `position: relative` so the prompt
    overlay (re-parented there at runtime) can use absolute inset:0
    to cover tabs + panel body.
  - .ai-onboarding-wrap claims the same flex slot as .ai-chat-messages
    when shown.
  - .ai-history-open also hides the wrap so opening the history
    dropdown takes the panel body cleanly.
  - .ai-onboarding-prompt-overlay (top-level rule, not nested under
    the wrap, so the styles apply after the runtime reparent)
    matches Phoenix Code's panel chrome — neutral grey card on
    @bc-ai-sidebar-bg / @bc-ai-input-border, header strip with
    title + × close, full-bleed flush textarea, action row with
    quiet text Cancel and an icon-only send button mirroring
    .ai-send-btn. Explicit focus reset (border/outline/box-shadow:
    none) so the global textarea:focus rule can't shift the
    dialog when the user clicks in.
  - Light entrance animations (overlay fade, card pop).
* strings.js: AI_CHAT_ONBOARDING_REVIEW_PROMPT ("Ready to build")
  and AI_CHAT_ONBOARDING_SEND.
