Subject: [PATCH] fix(rpc): show the real base endpoint in RPC response URL,
 not a fabricated path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The LIVE RESPONSE header and the expanded-response modal on RPC operation
pages displayed a synthetic URL like
`https://rpc.mainnet.fastnear.com/account/view_account`. NEAR JSON-RPC does
not route by path — every method is a POST to the base endpoint with the
method in the JSON body — so that `/account/view_account` slug never matched
the actual request that the page fires.

Drop the buildRpcEndpointUrl helper (which derived the slug from the canonical
docs path) and report the real endpoint the request POSTs to
(selectedNetworkDetails.url), which also correctly tracks mainnet/testnet. The
change is runtime-display only; REST/HTTP pages, which have genuine paths, are
untouched.

Update the two playwright assertions that had codified the old behavior.
