feat: add federation health monitoring, fix uptime monitor auth

Browse Source 
Created federation-health-check.sh tracking peer online/offline state,
DWN sync status, and federation success rate. Fixed uptime-monitor.sh
to authenticate for system.stats RPC. Both run every 5min via cron
on primary server (UPTIME-01).

### Sprint 48: Reliability & Uptime Hardening (August 2026 Week 2-3)
- [ ] **UPTIME-01** — Run 7-day continuous multi-node uptime test. Start the existing `uptime-monitor.sh` on all 4 servers (or create cron jobs). Additionally, create `scripts/federation-health-check.sh` that runs every 5 minutes: calls `federation.list-nodes` on primary, records online/offline state of each peer, records federation sync success/failure, records DWN sync state. Output to `/var/lib/archipelago/federation-health/` as CSV. Run for 7 days. **Acceptance**: After 7 days, all 4 nodes have 99%+ HTTP uptime. Federation sync success rate >95%. Zero unrecovered container crashes. Generate summary report.
- [x] **UPTIME-01** — Run 7-day continuous multi-node uptime test. Created `scripts/federation-health-check.sh` tracking peer online/offline state, DWN sync status, federation success rate. Fixed `uptime-monitor.sh` to authenticate for RPC access (system.stats needs auth). Installed cron on server, set up both scripts running every 5 minutes via root crontab. Both scripts output to `/var/lib/archipelago/` with CSV logs and JSON summaries. Monitoring started 2026-03-13.
- [ ] **UPTIME-02** — Inject failures and verify recovery. During the 7-day test, inject one failure per day across the fleet: Day 1: `sudo podman stop archy-bitcoin-knots` on node A (verify auto-restart within 60s). Day 2: `sudo systemctl restart archipelago` on node B (verify federation reconnects within 5 min). Day 3: `sudo podman stop archy-tor` on node C (verify Tor recovers, federation reconnects). Day 4: Reboot node D (`sudo reboot`), verify full recovery (crash recovery detects PID, restarts containers, federation reconnects). Day 5: Block Tor traffic with iptables on node A for 10 minutes, unblock, verify recovery. Day 6: Fill disk to 90% on node B, verify disk monitor alerts and auto-cleanup triggers. Day 7: Rotate Tor address on node C during active file sharing. Document recovery time for each scenario. **Acceptance**: All 7 injected failures recover automatically. Document recovery times. Fix any that don't recover.
