Changes ProcessEnv import from non-existent 'node:process' module
to use built-in NodeJS.ProcessEnv type.
Fixes TypeScript compilation error:
Module '"node:process"' has no exported member 'ProcessEnv'
Also adds NodeJS to ESLint globals to resolve no-undef warning.
All services now healthy and operational.
