Dial /v1, the only prefix luxd serves

luxd pins baseURL="/v1" (node/server/http/server.go:33) and has never
served /ext, so both exported constructors — plugin/evm/client.NewClient
and warp.NewClient — built a path no node answers. They are the seam
every out-of-tree caller goes through: cli/pkg/utils/staking.go,
sdk/validatormanager/uptime.go and netrunner/api all hand them a bare
node URI, and staking.go's own SplitRPCURI already parsed /v1/bc/<id>/rpc.
Those callers were already on /v1; this package was the lagging outlier,
so fixing it here fixes all of them without touching one.

Also corrects the simulator's default websocket endpoint, the hardhat
default, and the docs — including api.testnet.lux.network, which does not
serve RPC at all. The testnet host is api.lux-test.network (chainId
0x17870). Prefix-only sweeps miss that class of error.

Tests pin the constructed path against an httptest server, with both an
alias and a blockchain ID, so a future prefix change fails loudly instead
of silently 404ing in production.
