v5.1.7 - Upgrade pypowerwall proxy to v0.16.2t97

Proxy Upgrade — pypowerwall v0.16.2t97

Upgrades the bundled pypowerwall proxy from v0.15.13t94 → v0.16.2t97.

Highlights

• TEDAPI SolarOnly fallback auto-recovery — when TEDAPI connectivity is lost, the proxy now detects the failure and automatically continues serving solar data. When connectivity returns, it recovers automatically with exponential backoff. Enable via PW_TEDAPI_RECOVERY=yes. Fixes #821.
  • /health and /stats now include a fallback_mode block (is_fallback_mode, reason, entered_at, recovery_attempts, last_recovery_attempt)
  • POST /health/reset resets fallback state and triggers immediate recovery
• Fix: Docker HEALTHCHECK — now uses curl instead of wget (not available on Alpine); the prior check always failed silently
• Fix: v1r WiFi-fallback responses — normalized at the transport boundary, fixing silently empty/incorrect data when LAN→WiFi fallback fires
• Feat: get_firmware_version() — unified across V2024_06 and V2026_06 query sets and across basic/v1r transports

Files Changed

• powerwall.yml — pypowerwall image → jasonacox/pypowerwall:0.16.2t97
• VERSION — 5.1.6 → 5.1.7
• upgrade.sh — version consistency
• RELEASE.md — v5.1.7 entry
