feat(morpho): route YV unwind liquidity alerts to the curation chat

[spalen0]

The "Insufficient unwind liquidity for YV collateral markets" alert is acted on by curation (rebalance the vaults, adjust market caps), not by the public morpho group — so it now goes to an internal curation chat.

🚨 ⚠️ Insufficient vbUSDT unwind liquidity for YV collateral markets on KATANA
🏦 Vaults: Gauntlet USDT, Yearn OG USDT (V2), Gauntlet USDT (V2)
💰 Withdrawable vbUSDT: $425,077.48
🔥 Total collateral at risk: $516,853.61
📊 Required with buffer: $646,067.02 (0.66x coverage)
💹 Markets:
- yvvbUSDT/vbUSDC: $516,853.61 at risk (2% shock, LLTV 86.0%)

Setup

One new env var, a standalone chat served by the DEFAULT bot:

TELEGRAM_CHAT_ID_CURATION=your-curation-chat-id

Until it's set on the runner, nothing changes — resolve_channel falls back to the morpho group, so a missing env var can't silently drop the alert.

Changes

• utils/telegram.py — new CURATION_CHANNEL and resolve_channel(channel, fallback).
• protocols/morpho/markets.py — the unwind alert is sent with channel=resolve_channel(CURATION_CHANNEL, PROTOCOL). Its protocol stays morpho, so the emergency-withdrawal dispatch hook still fires and alert records keep their origin.
• Docs: .env.example, protocols/morpho/README.md, monitoring.yaml.
• Tests: two cases in tests/test_morpho_markets.py covering the curation route and the morpho fallback.

Scope

Only this alert moves. Every other morpho alert (bad debt, allocation, risk level, per-vault low liquidity) still goes to the morpho group.

Testing

ruff check/format clean; full suite passes (717 passed, 4 skipped).
