fix: task export only works every other time

[krushnarout]

Summary

• Fix task auto-export only working every other time (1 out of 2, 2 out of 4 exports succeeding)
• Fix task integration state not being loaded on the action items page

Root cause

The backend auto-sync spawns daemon threads that each call asyncio.run(), creating a new event loop per call. But all threads shared a global httpx.AsyncClient (via get_http_client()). When the first thread's event loop closes, the client's connections become stale. The next thread reuses the same client with dead connections → request fails. Then the stale connections get cleaned up → next call works again. This produces the alternating success/failure pattern.

Fix

• task_sync.py: Create a fresh httpx.AsyncClient (via async with) per auto-sync call instead of reusing the global singleton
• task_integrations.py: Add optional client parameter to _create_task_internal, ensure_valid_oauth_token, and refresh_oauth_token so the fresh client is threaded through the entire call chain
• Existing API endpoint callers are unaffected (they don't pass client, so the global is used as before)

Test plan

• Create action item → verify it appears in external app (Todoist/Asana/Google Tasks/ClickUp)
• Create 2nd action item immediately after → verify it also exports
• Create 4+ items in sequence → verify all export consistently

Code Review

This pull request fixes an issue where task integrations were not loaded, causing task exports to fail. The change introduces logic in ActionItemsPage to proactively load the TaskIntegrationProvider state on initialization. This is a good fix that directly addresses the problem. I've added one comment regarding a potential race condition in the data loading logic to make it more robust.

@krushnarout Quick nudge: tests/demo evidence is required before review. Please add test output or a short screenshot/video, then flip this back to ready. Thanks.

What was fixed

Problem: Task auto-export to external apps (Todoist, Asana, Google Tasks, ClickUp) only worked every other time — create 2 items, only 1 exports; create 4, only 2 export.

Root cause: The backend auto-sync runs in daemon threads using asyncio.run(), which creates a new event loop each time. But all threads shared a single global httpx.AsyncClient. When the first thread's event loop closed, the client's connections became stale. The next thread reused the same client with dead connections → request failed. Then stale connections got cleaned up → next call worked again, producing the alternating pattern.

Fix (2 files):

• backend/utils/task_sync.py — Create a fresh httpx.AsyncClient per auto-sync call (via async with) instead of reusing the global singleton
• backend/routers/task_integrations.py — Add optional client parameter to _create_task_internal, ensure_valid_oauth_token, and refresh_oauth_token so the fresh client flows through the entire call chain. Existing API endpoint callers are unaffected (backward compatible).
