tools: relabel upstream host in the mock so the Channels screen populates

Browse source 
The app decides a video/channel is "local" by matching its host against the
instance host; relabel peertube2.cpy.re to the proxy's own host in the JSON
(host fields only, never URLs) and map handles back when proxying, so the
Channels screen and channel pages work through the mock.
