Implemented RFC 9429 §4.3 WHEP Link header support.

Changes:

app/webrtc/subsystem.go: Added ICEServerURIs() []string method exposing coreCfg.ICEServers for use by the handler.
app/webrtc/handler.go (Subscribe): Emit one Link: <uri>; rel="ice-server" header per configured ICE server URI immediately before the 201 response, so browsers can discover STUN/TURN without a separate signalling round-trip.
app/webrtc/handler.go (addCORS): Added Link to Access-Control-Expose-Headers so cross-origin fetch() calls can read the Link headers.
app/webrtc/handler_test.go: Added TestSubsystem_ICEServerURIs_ReturnsConfiguredURIs and TestAddCORS_ExposesLinkHeader.
