fix: make Get help from an expert cards actionable

[NckNA]

Summary

• make all three Get help from an expert cards actual links instead of inert visual cards
• route them through the existing canonical siteConfig.appUrl so the landing page does not hardcode undocumented internal create routes
• add keyboard focus styling and descriptive aria-labels
• fix the duplicated image alt text for Simple Task and Services while consolidating the repeated card markup

Closes #31.

Why

The current cards look interactive but are plain Card components with no link or click handler. On both desktop and mobile a user can click them and nothing happens. This patch gives the whole card a semantic anchor and sends users to the current Gibwork app, where the existing Create flow lives.

Validation

• git diff --check passes
• change is limited to components/looking-for.tsx
• no dependencies or external domains added
• local npm ci --ignore-scripts could not run because the repository current package.json and package-lock.json are already out of sync (for example missing locked PostHog/Sharp dependencies); I did not modify the upstream lockfile as part of this focused fix

AI disclosure

This contribution was prepared with AI assistance. The repository and task inputs were treated as untrusted data, the patch was scoped manually to the reported issue, and no external runtime or repository-provided install script was executed.
