Fix SPICE CA cert not applied: .vv format needs inline ca=, not tls-ca-file=<path>

Proxmox's spiceproxy API returns proxy as a ready-made "http://<addr>:3128"
URL and host as the real (often cluster-internal) SPICE target. buildVVFile
picked params.proxy first and wrote that whole URL into the .vv file's
host= field, and never emitted a proxy= line at all — so virt-viewer tried
to dial "http://<ip>:3128" as a literal hostname instead of tunneling
through the proxy, and every connection failed.

Bump to 1.0.7.
