COHK Main Hub v5 — Upload-Ready

Upload these 3 files to same folder on your host — links work after upload. No more broken container:// links. Small fixes: edit locally, re-upload same 3 files.

📄 V1 — Invoices / PO / Quotes (Original Client Portal)Open → 🚢 Trading Hub v4 FIXED — 100s Trades, Click row to reload, Expenses linked to contractOpen → 🏠 Main Hub (this page)Refresh

✅ FIXED FOR UPLOAD:
- Old links used container:///mnt/data/... → works only in preview, breaks after upload
- New links use ./v1-invoices.html and ./trading-hub.html → works after upload if 3 files in same folder
- Also added fixed top nav bar in both V1 and Trading Hub linking back to each other via relative paths
- Keep 2 pages separate: V1 (DB) + Trading Hub (Local) = less errors, as requested
- For local preview in Meta AI, also keep container:// fallbacks in same files

📦 Upload these 3 files:
index.html (this hub)
v1-invoices.html (V1 portal with nav)
trading-hub.html (Trading Hub with nav + click reload fix)

All in same folder → navigation works after upload.
