Docker compose build fails: lockfile excluded and pnpm latest breaks install #59

Problem

Running docker compose build from a fresh clone fails before containers can start.

I can reproduce two blockers in sequence:

1. .dockerignore excludes pnpm-lock.yaml, but Dockerfile copies it (COPY package.json pnpm-lock.yaml ...). Build fails with:
   • failed to calculate checksum ... "/pnpm-lock.yaml": not found
2. After allowing the lockfile into context, build still fails because Dockerfile uses corepack prepare pnpm@latest --activate, which currently resolves to pnpm v11. With v11, install errors out with:
   • [ERR_PNPM_IGNORED_BUILDS] Ignored build scripts: esbuild@0.27.7

Steps to reproduce

1. Clone repo
2. Run docker compose build

Expected

Docker images build successfully from a clean clone.

Suggested fix

• Do not ignore pnpm-lock.yaml in .dockerignore
• Pin pnpm in Dockerfile to a known working major/minor (e.g. v10), instead of latest

I prepared a PR with this fix.
