ci: add 11 missing packages with tests to CI workflow

[pyramation]

Summary

Re-implements the changes from PR #633 which was closed due to test hanging issues (now fixed in PR #634). This adds 11 packages with tests that were missing from the CI test matrix:

• graphql/server-test
• graphql/env
• graphql/server
• graphql/test
• graphql/playwright-test
• packages/csv-to-pg
• packages/smtppostmaster
• postgres/drizzle-orm-test
• uploads/etag-hash
• uploads/etag-stream
• uploads/stream-to-etag

Also updates the graphql/env test snapshot to include new smtp configuration fields that were added to the codebase.

Note: jobs/knative-job-worker is commented out (temporarily disabled per user request).

Updates since last revision

• Fixed IPv6/IPv4 mismatch issue: The server was binding to localhost which resolves to ::1 (IPv6) on some systems, but supertest connects to 127.0.0.1 (IPv4), causing ECONNREFUSED errors. Now explicitly binds to 127.0.0.1.
• Fixed race condition: Added wait for 'listening' event before accessing httpServer.address() (which was returning null).
• Fixed GraphQL query field names: Updated test queries from allUsers/allPosts to users/posts to match the actual PostGraphile-generated schema.
• Updated test assertions: URL pattern expectations now match 127.0.0.1 instead of localhost.
• Clarified rollback test: The pg client (superuser) doesn't participate in the db client's transaction rollback - test now correctly demonstrates this behavior.

Review & Testing Checklist for Human

• Verify IPv6/IPv4 fix works in CI environment - The change from localhost to 127.0.0.1 is the core fix; confirm tests pass in CI
• Review graphql/server-test/src/server.ts - verify the listening event wait logic and IPv4 binding are correct
• Verify the GraphQL field name changes (users vs allUsers) match the actual schema generated by PostGraphile
• Review the rollback test change - it now asserts data persists (count=3) rather than rolls back (count=2); confirm this is the intended behavior for testing pg client vs db client differences
• Verify all 11 new CI jobs run and pass

Suggested test plan: Wait for CI to complete and verify all 11 new jobs pass, particularly graphql/server-test. If tests fail with connection errors, the IPv6/IPv4 fix may need adjustment for that environment.
