rpc: make uptime monotonic across NTP jumps

Browse Source 
Compute `uptime` from `SteadyClock` so it is unaffected by system time changes after startup.

Derive GUI startup time by subtracting the monotonic uptime from the wall clock time.

Add a functional test covering a large `setmocktime` jump.
