test: watchdog E2E in 1.5s instead of 22.7s (tunable poll interval)

Browse Source 
server.ts gains BROWSE_WATCHDOG_INTERVAL_MS (floor 50ms, default 15s
unchanged). The #994 stay-alive test runs a 250ms tick and waits for the
stay-alive log line instead of blind-sleeping 2s + 20s past the
production interval.
