Name the card that ran, and say what to install

Browse Source 
Two things the first pass got wrong.

The card was named out of whichever listing came first, so a machine
with both a CUDA build and a Vulkan loader could have its card named
from the wrong one. Worse, whisper numbers every device it can see in
one sequence while the handle carries the backend's own index: a
processor-only build lent a Vulkan backend through GGML_BACKEND_PATH
reports "device 1: Vulkan0", and reading that listing by the handle's
digit names whatever sat in slot zero. The backend's own enumeration is
asked first now, because it is the only one indexed the way the handle
is, and whisper's listing is a fallback taken only when it names
exactly one card.

And "this build carries no graphics backend" left the reader with
nowhere to go. It is the one case with a fix worth naming: whisper.cpp
publishes no build that reaches a card on Linux, and program_path runs
a copy from the system ahead of the downloaded one, so installing one
is the whole remedy. Server.state() now says which copy is running,
and the line says so only when it is Dikte's own download; a system
build that cannot reach the card gets the shorter sentence, since
installing it again would change nothing.
