Add GET /connections/{connection_id}/health to validate remote database
connectivity. Each backend reuses its existing connection code and runs
a minimal probe (SELECT 1 or list_namespaces). Returns 200 with
{healthy, error, latency_ms}; HTTP 404 only for unknown connection_id.
Includes a 10s timeout at the dispatch level and a 5s connect_timeout
for Postgres to prevent hanging on unreachable hosts.
The 10s tokio::time::timeout wrapper handles all backends uniformly.
