fix(docker): copy testing/e2e/package.json for frozen lockfile install

[07prajwal2000]

Summary

• testing/e2e is declared as a workspace in root package.json, but no Dockerfile's deps stage copied testing/e2e/package.json, so bun install --frozen-lockfile failed with Workspace not found "testing/e2e" in every image build (kit, admin, worker-compiled).
• Adds COPY testing/e2e/package.json testing/e2e/package.json to all three Dockerfiles' deps stages, alongside the other workspace manifests.
• Second, independent bug found while verifying the fix with a real docker build: bun run build (invoked by every Dockerfile after bun install) also failed, in apps/web, on a genuine next build type-check error unrelated to the lockfile. whereConditionSchema's attribute/value had become a tagged { kind, value } union (column vs literal), but the db block settings panels (delete.tsx, getAll.tsx, getSingle.tsx, update.tsx) still passed those tagged objects straight through to ConditionsEditor, which expects flat string | number | boolean. Fixed by unwrapping .value on read and re-tagging (column for lhs, literal for rhs) on write — the same approach apps/portal's serializeDbConditions/parseDbConditions already use for the current db block settings panels.

Test plan

• Reproduced the lockfile failure by simulating the deps stage COPY list in an isolated dir and running bun install --frozen-lockfile — failed with Workspace not found "testing/e2e"; fix resolved it.
• bun run --cwd apps/web build and full bun run build (all 4 workspace build tasks) pass after the apps/web fix.
• Built docker/worker-compiled/Dockerfile end-to-end locally (docker build) — succeeded.
• Built docker/kit/Dockerfile end-to-end locally (docker build, all 3 stages: deps → build → production) — succeeded. Test images removed afterward (docker rmi).
