feat(e2e): implement end-to-end testing framework with database preparation and lifecycle management

- Add E2ESchemaDatabaseConfig interface for database configuration validation. - Implement assertE2ESchemaDatabaseConfig function to enforce schema requirements. - Create prepareE2ESchema function to handle schema preparation and initialization. - Develop E2E lifecycle management functions to provision, prepare, and run tests. - Introduce Docker Compose setup for E2E database environment. - Add Playwright configuration for E2E testing. - Implement various test cases to validate E2E schema preparation and lifecycle. - Create utility functions for environment variable management and database assertions. - Establish smoke tests to verify initial data setup and integrity.

-# Infraestructura E2E

-Suite de Playwright para navegador, frontend, backend y MariaDB E2E. Aún no contiene pruebas funcionales.
+Suite Playwright de navegador que valida frontend, backend y MariaDB reales. Es distinta de los tests HTTP/API integration de `apps/server/src/testing/http`, cuyo runtime y lifecycle son independientes.

 ## Estructura

@ -8,11 +8,15 @@ El primer nivel debe coincidir exactamente con el módulo propietario en `module

 ## Variables y base de datos

-Copia `apps/server/.env.e2e.example` a `apps/server/.env.e2e` y completa una MariaDB exclusiva E2E; `DB_NAME` nunca debe ser la base de desarrollo. Copia `apps/web/.env.e2e.example` a `apps/web/.env.e2e`.
+Copiar `apps/server/.env.e2e.example` a `apps/server/.env.e2e` y completar sus valores locales. Copiar `apps/web/.env.e2e.example` a `apps/web/.env.e2e`.

-El backend arranca con `node --env-file=.env.e2e`, que prevalece sobre `.env`. La plantilla usa `DB_SYNC_MODE=none`; no hay reset, seed ni operación destructiva en esta fase. Las futuras operaciones destructivas deberán rechazar cualquier base que no sea E2E.
+El modo oficial exige `NODE_ENV=test`, `DB_NAME` con prefijo `factuges_erp_e2e_`, `DB_SYNC_MODE=none`, backend en el puerto `3002`, frontend en `http://127.0.0.1:5173` y frontend apuntando a `http://127.0.0.1:3002/api/v1`. Estas validaciones evitan fallbacks a desarrollo.

-`E2E_BASE_URL` permite usar un stack E2E ya iniciado y evita levantar procesos locales. Futuras credenciales: `E2E_USER_EMAIL` y `E2E_USER_PASSWORD`, nunca versionadas.
+El launcher oficial crea una MariaDB `mariadb:lts-noble` exclusiva con puerto dinámico, credenciales generadas y nombre único; comprueba su readiness y `SELECT 1`. Después prepara el schema mediante la composición modular real del backend y `sequelize.sync()` sin `force`, `alter`, migrations ni SQL manual. El backend posterior recibe la misma DB con `DB_SYNC_MODE=none`, por lo que no la modifica. El launcher destruye exactamente su proyecto Compose al terminar, incluso si falla la preparación o Playwright. No usa la MariaDB remota anterior ni volúmenes persistentes.
+
+La preparación P3 crea sólo schema. P4 añade antes de Playwright una cuenta E2E, compañía `factuges-e2e`, membership activa, rol admin y onboarding completado. Usa `E2E_USER_EMAIL` y `E2E_USER_PASSWORD`; no crea customers, suppliers, documentos ni series de escenario. El fichero `fixtures/company-certificates.json` es un JSON vacío versionado para que el backend E2E no dependa de certificados locales.
+
+`E2E_USER_EMAIL` y `E2E_USER_PASSWORD` son credenciales locales no versionadas.

 ## Ejecución

 ```

-Localmente se espera backend en `http://127.0.0.1:3002/api/v1/__ready` y Vite en `http://127.0.0.1:5173`.
+Los tres comandos oficiales arrancan su propio backend y Vite. Nunca reutilizan procesos existentes: si los puertos `3002` o `5173` están ocupados, la ejecución falla explícitamente.
+
+## Modo externo explícito
+
+Para depurar contra un stack ya iniciado se debe indicar deliberadamente el destino:
+
+```bash
+E2E_BASE_URL=https://e2e.example.test pnpm test:e2e:external
+```
+
+También existen `test:e2e:external:ui` y `test:e2e:external:headed`. Sólo estos comandos aceptan `E2E_BASE_URL`; los comandos oficiales lo rechazan.
+
+El modo externo no arranca procesos locales ni valida la infraestructura remota: es una herramienta deliberada de debugging y no sustituye al comando oficial.
