fix: resolve all CI/workflow failures for green PR builds #4675

What changed?

• Small fix
• Feature
• Refactor
• Infra / CI

Multiple independent failures prevented CI from passing on any PR: broken workflow YAML, PowerShell parse errors, TypeScript syntax/type errors, missing exports, and stale archive directories polluting compilation.

Workflow / CI

• d8-deploy.yml: fixed continue-on-error indentation (was at wrong YAML nesting level)
• protected-paths.ps1: moved param() before Set-StrictMode (PowerShell requirement)

Source fixes

• D8TV.tsx: removed stale type-declaration lines (tone?: string; etc.) inside function body
• __probe__/route.ts: try: any { → try {
• kv.ts: removed eslint-disable @typescript-eslint/no-var-requires — rule doesn't exist (no @typescript-eslint plugin in config)
• page.tsx: removed intentionally broken AutoRepairDemoWidget import
• d8kv.ts: added missing projectVideoKey export consumed by video page + embed component
• VideoStudioClient.tsx: non-null assertion on canvas ctx in closure (narrowing doesn't propagate)
• marketing-queue/page.tsx: typed useMemo return as Record<string, string> to satisfy HeadersInit
• (marketing)/_d8/D8Bits.tsx: added title/body/kicker props to D8Card (callers already passed them)

Build config

• tsconfig.json + .eslintignore: excluded 18 stale/archive dirs (~130 orphaned .ts/.tsx files)

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

• D8Card in (marketing)/_d8/ was a stripped-down copy missing props the marketing pages already relied on. Aligned it with src/app/_d8/D8Bits.tsx.
• .github/ALLOW_PROTECTED_PATHS added to unblock this PR since D8TV.tsx and marketing D8Bits.tsx live under protected paths.
• 4 pre-existing ESLint warnings remain (missing useEffect deps, <img> vs <Image>, async client component) — all non-blocking, out of scope.
