Migrate compliance-portal to the global ESLint config

The compliance-portal app still carried the per-workspace ESLint
scaffold that the rest of the monorepo dropped when linting was
centralized into the root eslint.config.mjs. It defined its own
local config, lint script, and lint-only devDeps, and was not
covered by the root lint script, so it was never linted.

Remove the local eslint.config.mjs, the lint script, and the
eslint/@probo/eslint-config devDeps, then add the app to the root
appDirs so the shared ts, react, and relay rule sets apply to it.

Replace the explicit per-directory list in the root lint script
with a bare `eslint .`, which the root config was already designed
for via its globalIgnores. Ignore pkg/** so the vendored minified
JS under the Go tree is not linted.
