birdnet-pipy: wait for upstream API before starting nginx

Browse Source 
Replaces the 0.6.6-3 sleep+ingress-file-loop in services.d/nginx/run
with bashio::net.wait_for on 127.0.0.1:5002 (core.api). Under
s6-overlay all services.d/* services start concurrently, so nginx
could accept requests before the API had bound its port — proxy paths
(/api/, /socket.io/, /internal/auth) would 502, and that 502 could be
cached by an upstream service worker / edge cache (e.g. Cloudflare-
fronted HA), leaving the UI blank.

Matches the sister-addon pattern (bazarr, jellyfin, radarr). Also
switches to `exec nginx` for proper s6 supervision of the nginx PID.

## 0.6.6-4 (2026-05-02)
- Fix nginx startup: wait for the upstream API on `127.0.0.1:5002` before starting nginx, instead of the prior `sleep 5` workaround. Under s6-overlay all `services.d/*` services start concurrently, so nginx could begin accepting requests before `core.api` had bound its port — `/api/`, `/socket.io/`, and `/internal/auth` would then return 502, and that 502 could be cached by an upstream service worker / edge cache (e.g. behind Cloudflare-fronted HA), leaving the UI stuck blank. Uses `bashio::net.wait_for` to match the pattern in sister addons (`bazarr`, `jellyfin`, `radarr`).
## 0.6.6-3 (23-04-2026)
- Minor bugs fixed
## 0.6.6-2 (23-04-2026)
