MechaCat02 0a3877be51 chore: full hop-by-hop header strip and 60s timeout on /api/* proxy ...

The SvelteKit proxy was only stripping host + content-length; the rest
of RFC 7230 §6.1 (connection, keep-alive, proxy-authenticate,
proxy-authorization, te, trailer, transfer-encoding, upgrade) leaked
through to axum. Axum doesn't emit them so the impact is theoretical,
but the proxy should be RFC-conformant. Also adds an AbortController
with a configurable 60s timeout (BACKEND_PROXY_TIMEOUT_MS) so a
wedged backend can't hang the browser request indefinitely — failures
surface as the standard 502 upstream_unavailable envelope.
