Add Drizzle ORM and Neon database setup.

[supermarios77]

This PR introduces the database layer for Linglix using Drizzle ORM and Neon serverless Postgres.

Changes:

• Installed drizzle-orm, @neondatabase/serverless, drizzle-kit
• Added drizzle.config.ts for schema/migrations
• Defined minimal initial schema (src/db/schema.ts) with basic tables
• Created DB client (src/db/index.ts) using neon-http driver (serverless-friendly)

Why this way:

• Drizzle for type-safe, lightweight, SQL-first ORM (edge-compatible, fast cold starts)
• Neon for serverless Postgres (scales to zero, low cost early)
• neon-http driver chosen for simplicity in Next.js API routes/server components

Testing:

• Local: pnpm drizzle-kit push:pg → tables appear in Neon console
• Queried users table via simple API route → works in dev
• No breaking changes to existing code

Next steps:

• Integrate with BetterAuth (auth tables/schema)
