fix(deps): pin playwright to 1.62.1 and sync docker test image

Playwright was previously pinned with a caret range (^1.61.1), which
allowed pnpm to silently resolve a newer minor version after the
lockfile was regenerated. This caused a version mismatch with the
Docker test image, which still referenced 1.61.1.

- packages/luna-charts/package.json: pin playwright to 1.62.1 exactly
- Dockerfile.test: bump base image to v1.62.1-noble to match

pnpm-lock.yaml
