Re-enable disabled lint rules and right-size CI runners (#18461)

## Summary

- Re-enable one lint rule that was temporarily disabled during the
ESLint-to-Oxlint migration:
- **`twenty/sort-css-properties-alphabetically`** in twenty-front — 578
violations auto-fixed across 390 files
- Document why **`typescript/consistent-type-imports`** cannot be
auto-fixed in twenty-server: NestJS relies on `emitDecoratorMetadata`
for DI, so converting constructor parameter imports to `import type`
erases them at compile time and breaks dependency injection at runtime
- Right-size CI runners, reducing 8-core usage from 18 jobs to 3:

| Change | Jobs | Rationale |
|--------|------|-----------|
| **Keep 8-core** | `ci-merge-queue/e2e-test`,
`ci-front/front-sb-build`, `ci-front/front-build` | Heavy builds needing
max CPU + memory (10GB NODE_OPTIONS, full Storybook webpack bundling) |
| **8-core → 4-core** | `ci-server` (build, lint-typecheck, validation,
test, integration-test), `ci-front/front-sb-test`,
`ci-zapier/server-setup`, `ci-sdk/sdk-e2e-test` | Already sharded into
10-12 parallel instances, I/O-bound (DB/Redis), or moderate single
builds |
| **8-core → 2-core** | `ci-emails/emails-test` | Trivially lightweight
(build + curl health check) |
| **Removed** | `ci-front/front-chromatic-deployment` | Dead code —
permanently disabled with `if: false` |

- Fix merge queue CI issues:
- **Concurrency**: Use `merge_group.base_ref` instead of unique merge
group ref so new queue entries cancel previous runs
- **Required status checks**: Add `merge_group` trigger to all 6
required CI workflows (front, server, shared, website, docker-compose,
sdk) with `changed-files-check` auto-skipped for merge_group events —
status check jobs auto-pass without re-running full CI
- **Build caching**: Add Nx build cache restore/save to E2E test job
with fallback to `main` branch cache for faster frontend and server
builds

## Test plan

- [ ] CI passes on this PR (verifies lint rule auto-fix works)
- [ ] Verify 4-core runner jobs complete within their 30-minute timeouts
- [ ] Verify merge queue status checks auto-pass (ci-front-status-check,
ci-server-status-check, etc.)
- [ ] Verify merge queue E2E concurrency cancels previous runs when a
new PR enters the queue
