fix(rpm): drop %attr(,,user) on config files to avoid dnf silent filter

Using %attr(,,cortex) / %attr(,,neuron) on config files caused rpm's
auto-dep-generator to emit Requires: user(name) and group(name) on
each package. When those Requires couldn't be resolved — whether due
to sysusers Provides mismatches, missing GPG keys, or dnf5 cache
state — dnf5 silently filtered the package out of the candidate set
and reported "Nothing to do" rather than an unsatisfied-dep error.

Adopt the pattern that already works reliably across our infra
(grenade/monsoon): ship config files as default root:root with 0644
perms, don't declare user/group ownership in the rpm file list.
systemd-sysusers still creates the service user via the shipped
sysusers.d file; the service drops to that user at runtime via the
User= directive in the unit.

This removes the user(cortex)/user(neuron) Requires entirely, which
is the root cause of the dnf5 filtering. File permission tightening
can be reintroduced later — either via a separate secrets file with
different mode bits, or by moving secret material to /var/lib/<svc>/
where the service drop-privileges account already has write access.
