X OAuth Live Import: API endpoints not implemented

[NickPlaysCrypto]

Bug

The Import page's Live Import tab always shows "X OAuth not configured" and "Could not connect to the server" — even after successfully saving X OAuth credentials in Settings.

Root Cause

The API endpoints that the Import page calls do not exist. The LiveImportTab component fetches from /api/import/x-oauth/* routes that have never been implemented.

What happens:

1. User saves X OAuth Client ID + Secret in Settings → ✅ Saved to DB correctly
2. GET /api/settings returns hasXOAuth: true → ✅ Credentials confirmed
3. Import page calls GET /api/import/x-oauth/status → ❌ 404 — route doesn't exist
4. The generic .catch() handler fires → displays "Could not connect to the server"

Expected endpoints (none exist):

• GET /api/import/x-oauth/status — Check OAuth config & connection
• GET /api/import/x-oauth/authorize — Start OAuth flow
• GET /api/import/x-oauth/callback — Handle OAuth redirect from X
• POST /api/import/x-oauth/disconnect — Remove token
• POST /api/import/x-oauth/fetch — Fetch bookmarks via X API

Evidence

The /app/api/import/ directory only contains bookmarklet/, live/, and twitter/ — no x-oauth/ directory.

The Settings page even references the callback URL (/api/import/x-oauth/callback) but the route was never created.

Steps to Reproduce

1. Create an X Developer app with OAuth 2.0
2. Go to Siftly Settings → paste Client ID and Client Secret → Save
3. Go to Import → Live Import tab
4. See "X OAuth not configured" and "Could not connect to the server"

Additional Notes

• The error message is misleading — "Could not connect to the server" is actually a 404 caught by a generic .catch() block (line 710 of app/import/page.tsx)
• The Bookmarklet and Console import methods work as alternatives

Environment

• Siftly v0.1.0
• Next.js 16.1.6
• macOS / Chrome
