fix(server): Use tsconfig.json for serverTestHelpers rollup build (#138)

* fix(server): Use tsconfig.json for serverTestHelpers rollup build

The serverTestHelpers rollup config was using `tsconfig: false` with inline
compiler options, which bypassed TypeScript project references. During npm
workspace publishing, this caused the build to fail to resolve the updated
`@atxp/common` types (specifically the new `createSpendPermission` method
on the Account type).

By using the proper tsconfig.json, the build correctly follows project
references and resolves workspace dependencies.

* fix: Remove corrupted nested @atxp packages from package-lock.json

The package-lock.json had nested node_modules entries that pointed to npm
registry versions instead of using local workspace packages:
- packages/atxp-base/node_modules/@atxp/client
- packages/atxp-base/node_modules/@atxp/common
- packages/atxp-client/node_modules/@atxp/common
- packages/atxp-express/node_modules/@atxp/common

This caused CI typecheck to fail because it was using @atxp/common@0.10.4
which doesn't have the createSpendPermission method.
