- After generation, toolbar shows "Save to Flow Library" button
(replaces "Import to Editor")
- Button shows "Saving..." spinner state during API call
- Generate button shows animated spinner during generation
- Backend /import endpoint always creates a new Tree record
(removed generated_tree_id idempotency check)
- Navigates to tree editor after successful save

- C1: Fix race condition in handleReset — await abandonSession before
starting new session to prevent store state corruption
- I1: Extract error messages from Axios response.data.detail instead of
generic error.message — users now see helpful backend messages (quota
limits, message caps, etc.)
- I2: Add isGenerating guard in generateTree store action to prevent
concurrent generation requests on double-click
- I3: Add isResponding guard in sendMessage to prevent concurrent sends
- M5: Remove redundant type casts on flowType
- M6: Add rate limiter to DELETE /sessions/{id} for consistency

Tests cover session create, send message with tree update, get session,
abandon, 404 on missing session, and 503 when AI disabled.
Fixed: ai_usage.conversation_id has FK to ai_conversations, not
ai_chat_sessions. Chat builder now passes conversation_id=None and
tracks session reference in extra_data.chat_session_id.

6 endpoints: create session, send message, get session, generate tree,
import to editor, abandon. Quota service daily limit updated to include
chat builder generation types.
