feat(packaging): nix web console + plugin/script runner everywhere; fix tray zbus/tokio crash

Ship the management web console and the plugin/script runner across the packaging
matrix, and fix a Linux tray startup crash.

- nix: add punktfunk-web (Nitro SSR on bun) and punktfunk-scripting (Effect runner),
  with services.punktfunk.{web,scripting} modules. Both bun node_modules come from
  fixed-output derivations pinned to real deps hashes; patchShebangs the web
  node_modules so orval/paraglide/vite run in the sandbox. Validated on x86_64-linux
  (nix build .#punktfunk-{web,scripting,tray,host} all green).

- punktfunk-scripting now ships for deb/rpm/arch/nix/windows, mirroring the web-console
  mechanics (vendored bun on deb/rpm/arch, pkgs.bun on nix; one self-contained
  `bun build --target=bun` bundle). Opt-in: host Recommends it, but the systemd --user
  unit ships un-started (Windows registers its scheduled task disabled).

- fix(tray): build punktfunk-tray in its OWN cargo invocation on nix/rpm/arch. Cargo
  unifies features across one `cargo build`, so co-building the tray with the host pulls
  the host's ashpd->zbus/tokio onto the tray's shared zbus and it panics at startup
  ("there is no reactor running, must be called from the context of a Tokio 1.x
  runtime"). Isolated, the tray's zbus stays on async-io. The .deb already did this;
  runtime-verified on nix.
