refactor: rename package from mistralrs-server to mistralrs

Rename the RPM package from mistralrs-server-<flavour> to
mistralrs-<flavour> and the installed binary from mistralrs-server
to mistralrs, matching the upstream CLI binary name.

Adds Obsoletes/Provides for the old package name so dnf will cleanly
replace it on upgrade.
