test(e2e): make server e2e actually boot (ESM chain + Fastify adapter)

The previous jest-config fix let the module graph load further and exposed
two more reasons the server e2e never passed since it was added:

1. ESM transform chain: AppModule pulls in editor-ext -> @tiptap ->
   @sindresorhus/slugify -> @sindresorhus/transliterate / escape-string-regexp,
   plus p-limit -> yocto-queue — all ESM-only. Extend the e2e
   transformIgnorePatterns whitelist to transform them (scoped packages need
   both the pnpm `@scope+name` and nested `@scope/name` path forms, hence
   `@sindresorhus[+/][a-z0-9-]+`). Verified locally: the graph now fully
   transforms and resolves.

2. Wrong HTTP adapter: Docmost runs on Fastify (main.ts uses FastifyAdapter)
   and does not depend on @nestjs/platform-express, but the scaffold test used
   the default createNestApplication() (Express) and died with
   "@nestjs/platform-express package is missing". Switch the test to
   FastifyAdapter + getInstance().ready(), close in afterEach. Verified locally:
   createNestApplication + app.init() now proceed to the live Redis/Postgres
   connection (the infra CI provides via services + migrations).
