Omni/Dev: convert Ava to dynamic deployment

- Create Omni/Dev/Packages.nix with ava, deployer, deploy-manifest packages
- Add biz-deployer service to Beryllium.nix
- Remove static systemd service from Ava.nix (keep user/dirs setup)

Ava is now deployed via the mini-PaaS system rather than being a
static NixOS service. This enables fast Ava updates without full
NixOS rebuilds - just build, push closure, update manifest.
