chore(nix): refresh pnpm deps hashes for vela-cli 0.0.28

pnpm-lock.yaml moved @powerformer/vela-cli from 0.0.27-test.7 to 0.0.28, but nix/pnpm-deps.nix was not regenerated, so `nix flake check` failed with a fixed-output hash mismatch for both the daemon and web derivations.

Hashes taken from the Nix-reported expected values in CI run 30933223422 (nix is not available on this machine to run `pnpm nix:update-hash` locally); the merge of origin/main did not touch pnpm-lock.yaml, so those values still describe this tree.
