chore: add techbase to apps-archived

Integrated techbase (software comparison platform) into monorepo structure:
- Created NestJS backend with votes and comments modules
- Migrated from external Supabase to own PostgreSQL
- Set up Drizzle ORM schema for votes and comments
- Created API client replacing Supabase in Astro frontend
- Added environment configuration (port 3021)

Archived immediately as it's not yet ready for active development.
