fix(nix): watch scripts in nix-hashes workflow

[jerome-benoit]

Fixes #12817
Fixes #12811

nix/scripts/*.ts and patches/* are included in the node_modules derivation. Changes to these files invalidate output hashes but didn't trigger the workflow.

• Add nix/node_modules.nix, nix/scripts/**, and patches/** to paths trigger
• Remove non-existent install/ from fileset

Pull request overview

Updates the nix-hashes GitHub Actions workflow triggers so it reruns when Nix inputs that affect the node_modules derivation change, preventing stale nix/hashes.json updates.

Changes:

• Add nix/node_modules.nix to the workflow paths trigger.
• Add nix/scripts/** to the workflow paths trigger so script changes also trigger hash recomputation.
