Centralize ESLint into a single root config

Replace the duplicated per-workspace eslint.config.mjs files in
apps/console, apps/trust, packages/ui, and packages/eslint-config with
one root eslint.config.mjs that reuses the shared @probo/eslint-config
rule sets and scopes them per directory. Linting now runs from the repo
root, so pin the type-checked project service root and broaden the
import-x resolver to every workspace tsconfig (the #/* aliases live in
each app's tsconfig.app.json).

Drop the now-redundant per-package lint scripts and lint-only devDeps,
and add a root lint script that runs eslint over the four dirs with
multithreading restored via --concurrency auto, then lints n8n-node
through a direct workspace call. packages/n8n-node keeps its own
external preset.

Collapse the redundant lint-js -> npm-lint Makefile chain into a single
lint-js target and update the make docs accordingly.
