Merge feat/remote-builders into uconsole-cm5-incremental

Bidirectional remote building + rename uconsole-cm5 -> uConsole:
- Rename all uconsole-cm5 refs to uConsole (nixosSystem key, paths, module)
- Replace single-machine remote-builder module with multi-machine config
- Enable remote builder on lazyworkhorse -> uConsole (aarch64)
- Enable remote builder on uConsole -> lazyworkhorse (x86_64)
- Add builder system user + SSH key via agenix-rekey (secrets/builder_key.age)
- Add builder_key + gortium_password age secrets to all hosts
- Fix pre-existing bugs: missing modules in lazyworkhorse/cyt-pi,
  SSH config structure (hostKeys outside settings), cyt-pi inline user
- Remove obsolete openclaw-node service + module + age secrets
