server: remove dhiltgen/* compat redirect table

The redirect table was a stopgap for arches that llama-server (after
the runner removal) couldn't load because the Ollama-format GGUFs in
library/* differed from upstream. Every entry has now been superseded
by an in-process translator in llama/compat/, so the redirects are
dead weight: pulling library/<arch> works directly through compat
without rerouting the user to a republished blob.

Drops:
  * `compatModelRedirects` table (10 entries)
  * `applyCompatRedirect` / `reverseCompatRedirect` helpers
  * The single `applyCompatRedirect` call in resolveName
  * The `reverseCompatRedirect` call in PsHandler (the display name
    is now just the model's actual ShortName)
