BRIDGE_ORIGIN already used ${location.protocol}//; CONDUCTOR_ORIGIN was
hardcoded to http://, which would have broken under HTTPS deployment
with a Mixed Content block. Now both behave consistently — page over
HTTPS uses https for conductor calls and wss for the WS already (the
WS constant was already correct).
Triggered by SakuraFrp requiring HTTPS access (TCP tunnels reject
plain HTTP with 501). Tunnels now run with 自动 HTTPS enabled, so
browser hits https://...:14168 / :18900, and frontend needs to use
https in its constructed conductor URL.
Bump app.js?v=84 -> 86 (skipping 85 — that was an auth-gate-only bump).
