Sync Prisma CLI to 7.3.0 and migrate to Prisma 7 adapter pattern

[Copilot]

Addresses version mismatch between @prisma/client (7.3.0) and prisma CLI (6.17.0) identified in PR #10. Prisma 7 requires schema and client configuration changes.

Changes

• Dependencies: Upgraded prisma to ^7.3.0, added @prisma/adapter-pg, pg, and @types/pg
• Schema: Removed deprecated url property from datasource block (Prisma 7 requirement)
• Client Configuration: Migrated to adapter pattern with connection pool management

export class PrismaService extends PrismaClient {
  private readonly pool: Pool;

  constructor() {
    const databaseUrl = process.env.DATABASE_URL;
    if (!databaseUrl) {
      throw new Error('DATABASE_URL environment variable is not set');
    }
    
    const pool = new Pool({ connectionString: databaseUrl });
    super({ adapter: new PrismaPg(pool) });
    this.pool = pool;
  }

  async onModuleDestroy() {
    await this.$disconnect();
    await this.pool.end();
  }
}

Migration Context

Prisma 7 removed support for url in schema files. Direct database connections now require adapters (@prisma/adapter-pg for PostgreSQL) configured via the PrismaClient constructor.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
