steve da5b8435bc Add configurable allowed hosts for MCP remote access (KB_MCP_ALLOWED_HOSTS)
The MCP SDK's DNS rebinding protection rejects remote clients with 421
when the Host header isn't in the allowlist. Add KB_MCP_ALLOWED_HOSTS env
var (comma-separated IPs/FQDNs) to configure additional allowed hosts
while keeping localhost always permitted.
