attemptReconnect() connected with the stale cached conn.wsUrl. OAuth WS
tickets are single-use with a ~30s TTL, so the first sign-in (which goes
through boot() and re-mints via resolveGatewayWsUrl) succeeds, but every
reconnect (sleep/wake, network online, window refocus, socket drop, app
restart) reused a dead ticket and failed the WS upgrade with an opaque
"Could not connect to Hermes gateway" — even though backend resolution
(cookie + REST) reported ready.
attemptReconnect now mints a fresh ticket before connecting, mirroring
use-gateway-request.ts, and surfaces the reauth "sign in again" message
once on OAuth expiry instead of silently looping backoff against a dead
ticket. Local/token gateways are unaffected (re-mint is a no-op).
