Add configurable suffixes for GraphQL naming

[dmythro]

Mainly, wanted to add customizable naming to GraphQL schema and don't break existing code, so single entity suffix is still "Single", list suffix is "" by default.

My projects use singular naming for entities (eg "user", "account"), so naturally I'd like to see suffixes like this as default behavior is a bit confusing:

suffixes: {
  list: 's',
  single: '',
},

Pull Request Overview

This PR adds configurable suffixes for GraphQL naming to allow customization of query field names without breaking existing code. It maintains backward compatibility by keeping the default suffixes as an empty string for list queries and "Single" for single entity queries.

• Adds suffixes configuration option to BuildSchemaConfig type with optional list and single properties
• Implements suffix validation to prevent conflicts when both suffixes are identical
• Updates all database builders (SQLite, PostgreSQL, MySQL) to use configurable suffixes
