fix(installer): add absolute path resolution for Pro module in npx context (#508)

When running via `npx aios-core install`, require() resolves from the
npx temp directory, not process.cwd(). After bootstrap installs
@aios-fullstack/pro in the user's project, the existing 3 resolution
paths all fail. Add 4th path using absolute path to
process.cwd()/node_modules/@aios-fullstack/pro/license/ which is where
the bootstrap actually installs the package.
