chore: bump npm dependencies

[benfdking]

Combines five Dependabot npm updates into a single PR so the lockfile is regenerated once cleanly.

Package	From	To	Workspace
code-server	4.112.0	4.117.0	editors/code
@vscode/vsce	3.7.1	3.9.1	editors/code
postcss	8.5.13	8.5.15	playground
react-resizable-panels	4.0.16	4.11.2	playground
@tailwindcss/postcss	4.2.2	4.3.0	playground

pnpm-lock.yaml was regenerated via pnpm install --lockfile-only. bazelisk test //... passes locally.
