fix(freebsd): move chmod after daemon command in dashboard rc.d

The chmod 644 on pidfiles was injected mid-command between daemon(8)
and its arguments (--host, --port, etc.), causing the shell to pass
'chmod' as a subcommand argument to 'hermes dashboard', which
instantly crashed. Move it after the complete daemon invocation.

This caused the 502 Bad Gateway on ai.clawdie.si after restart —
dashboard process never started because it rejected 'chmod' as an
invalid dashboard subcommand.
