chain routes: /v1/bc -> /v1/chain

luxd serves chain routes under /v1/chain, and the node, cli and sdk releases
already ship it. The deployed gateways still answer the old prefix, so remote
reads break until they are redeployed; the estate moves together rather than
sitting half converted.

Lines that record an observation - a probe, a status code, a past release -
keep the prefix they were written against, as do URLs on hosts that are not
ours. Avalanche endpoints move to /ext/bc, which is the path that host serves.
