Add missing runtime dependencies and fix structure of dev shell

coderabbit:

1. The main buildInputs (libev, libunwind, curlWithGnuTls, sqlite) from lines 31-36
are not included—developers won't be able to build/link the project in this
shell.

2. autoconf-archive is duplicated (line 80 and already inherited via
nativeBuildInputs).

3. libevdev (line 77) is a different library than libev—verify this is intentional.
