fix(birdnet-pipy): simplify ingress to single <base href> rewrite

Upstream 0.6.3 consolidates deployment-path handling into a single
<base href> declaration in index.html with Vite base: './' and
relative paths for all internal URLs. The previous seven sub_filter
rules (href/src/'/api'/'/socket.io') are no longer needed — one
<base href> replacement is sufficient.

Also removes the incidental brittleness from byte-level sub_filter
matches in minified JS bundles (the '/stream/' rule inadvertently
double-prefixed the literal 'api.get("/stream/config")' string).
