fix: resolve all lint/build/CI errors across workflows #4690

What changed?

• Small fix
• Feature
• Refactor
• Infra / CI

CI was red on main due to accumulated syntax errors, type errors, and a malformed workflow file. Ten files fixed:

Syntax/parse errors

• D8TV.tsx — removed stray type annotations pasted into function body
• route.ts — try: any { → try {
• kv.ts — disabled nonexistent ESLint rule @typescript-eslint/no-var-requires

Type errors

• (marketing)/_d8/D8Bits.tsx — D8Card lacked title/body/kicker props used by all 4 marketing pages
• marketing-queue/page.tsx — useMemo return type widened to Record<string, string> for fetch headers compat
• d8kv.ts — added missing projectVideoKey export
• VideoStudioClient.tsx — canvas context type narrowing lost in closure; used intermediate binding

Build config

• tsconfig.json — excluded _archive/** (old backup dir was compiled)
• page.tsx — removed intentionally-broken AutoRepairDemoWidget import

CI workflow

• d8-deploy.yml — continue-on-error was at list-item indent instead of step-property indent:

# before (invalid)
      - name: Build gate
      continue-on-error: true
        run: npm run build

# after
      - name: Build gate
        continue-on-error: true
        run: npm run build

Quality gates (must be green)

• CI build is green
• No unexpected UI/design changes on Dominat8.com
• If protected paths changed: override label OR ALLOW_PROTECTED_PATHS file added with reason

Notes / risks

• All remaining ESLint output is warnings only (pre-existing: no-img-element, react-hooks/exhaustive-deps, no-async-client-component). No errors.
• _archive/ exclusion is additive to tsconfig.json; no impact on app source.
• CodeQL: 0 alerts.
