Make everything 1000x or 1000000x slower

Summary:
In the great pht() conversion, some strings like "123,456" are now being printed as numbers with "%d". These come out as "123" instead of "123,456".

Use "%s" and "PhutilNumber" to present numbers with comma groupings.

Test Plan:

• Viewed DarkConsole.
• Viewed conduit logs.
• Viewed daemon logs.
• Grepped for %d ms and %d us.
