Deleted unused e2e tests, mocks (`cuid2`, `jose`, `ml-kem`, `sha3`), and their associated jest configurations. Simplified services by ensuring proper dependency imports, resolving circular references, and improving TypeScript type usage for enhanced maintainability and testability. Upgraded Dockerfile base image to match new development standards.
Introduce modular PGP encryption utilities (`pgpEncrypted` type) for seamless handling of sensitive data in Postgres. Added utility `withAutomaticPgpDecrypt` to enable automatic decryption for selective columns, simplifying schema definitions.
Introduced centralized PGP encryption utilities and updated the `users` schema to enable automatic decryption for sensitive fields like `email` and `twoFactorSecret`.
Added `categories` and `favorites` database schemas with full type inference support. Integrated categories into `content` schema with new properties (`categoryId`, `slug`, `views`, and `usageCount`). Updated `tags` schema to include `userId` with reference to `users`. Exported new schemas in index for broader usage.
