ci: make eslint blocking now errors are at zero (TASK-21450)

[jjramirezn]

Summary

DS 10 (TASK-21450), item "eslint to 0 + hard gate". The advisory eslint job reached 0 errors after the sprint-155 cleanup, so this flips it to blocking before new errors creep back in:

• .github/workflows/tests.yml: remove continue-on-error from the eslint job and add it to ci-success.needs — a PR with any eslint error now fails CI.
• Remove the 6 eslint-disable directives the cleanup left unused (5 full removals, 1 trimmed rule list). The branch now lints with 0 errors and 0 unused-directive warnings.

The 58 remaining warnings are all react-hooks/exhaustive-deps; warnings do not fail the job. Fixing those risks behavior changes, so they stay out of scope. A warn floor (--max-warnings) can be added later if the team wants one.

Task

DS 10: lint ratchets in CI + eslint to 0 (TASK-21450) — this PR covers item 4; items 1–3 (counts ratchet, nuqs rule, apiFetch gate) come as separate PRs.

Risks / breaking changes

• Any PR into feat/design-system (and later dev/main once this merges through) fails CI on a single eslint error. That is the point, but branches created before the sprint-155 cleanup may go red on rebase.
• No runtime code changes — comment-only edits plus workflow config.

QA

• npx eslint . → 0 errors, 58 warnings (all exhaustive-deps), 0 unused directives.
• tsc --noEmit clean. Prettier clean on changed files.
• Full jest: same pass/fail set as the pristine branch tip (verified side-by-side; the 5 locally-failing suites are pre-existing local-env artifacts — CI is green on tip commit 3d1bed8).

Screenshots: N/A (no visible change)

📝 Walkthrough

Walkthrough

The pull request makes ESLint a required CI job and removes selected ESLint suppression comments from tests and source code.

Changes

ESLint CI enforcement

Layer / File(s)	Summary
Remove redundant ESLint suppressions src/app/(mobile-ui)/add-money/__tests__/add-money-states.test.tsx, src/components/Card/__tests__/PhysicalCardScreen.test.tsx, src/components/Global/InvitesGraph/index.tsx, src/i18n/app/__tests__/messages.test.ts	Selected ESLint suppressions were removed or narrowed. Test and runtime behavior remains unchanged.
Gate CI on ESLint .github/workflows/tests.yml	The ESLint job is now blocking. The ci-success job requires ESLint and reports its result in failure diagnostics.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to a19f8

The PR makes ESLint errors block CI; the remaining documentation mismatch could briefly confuse maintainers but does not create a merge-blocking risk.
