Refresh CLI example flag metadata and fix Feature prop usage

[Junnyyy]

TL;DR

Updated the CLI example to keep the temporary search flag metadata current and aligned the example app with the Feature component's flag prop.

What changed?

• Extended the search-platform fallback flag expiration in packages/cli/examples/flags.json
• Replaced the incorrect name prop with flag on Feature in packages/cli/examples/src/App.tsx
• Kept the example consistent with the current flag component API

How to test?

• Not run (not requested)
• Verify the example app still renders the conditional links correctly
• Confirm the Feature wrapper gates the Dashboard v2 link using flag="dashboardV2"

Why make this change?

• Prevents the CLI example from drifting out of sync with the documented flag component API
• Avoids stale example metadata for the temporary search fallback flag

Note

Low Risk
Example-only changes to flag metadata and a prop rename; no runtime product or security impact.

Overview
Updates the CLI example so it matches the current @latchflags/react API and keeps sample flag metadata current.

In packages/cli/examples/src/App.tsx, the Feature wrapper now uses flag="dashboardV2" instead of the invalid name prop, consistent with documented usage elsewhere in the repo.

In packages/cli/examples/flags.json, legacySearch.expiresAt is pushed from 2026-01-15 to 2027-01-15 for the temporary search fallback flag.
