ADDED Requirements

Requirement: Asset views SHALL display the estimated final package expiry

Asset detail and summary views using /api/c/v1/asset/info SHALL prefer estimated_final_expires_at over current_package_expires_at for the user-facing final expiry. The client SHALL use expiry_estimate_status, days_until_final_expiry, and is_expiring when those fields are returned, and SHALL NOT calculate a replacement final expiry locally.

Scenario: Exact final expiry is available

• WHEN expiry_estimate_status = exact and estimated_final_expires_at is present
• THEN the client SHALL display the estimated final expiry date
• AND the client SHALL display the returned remaining-day value when available

Scenario: Asset is approaching final expiry

• WHEN is_expiring = true or the backend returns an applicable expiry level
• THEN the client SHALL apply the existing expiry highlight/reminder presentation
• AND the client SHALL use the backend value rather than recalculating the threshold

Scenario: Final expiry cannot be estimated

• WHEN expiry_estimate_status is none, waiting_activation, or invalid_data, or the estimated date is null
• THEN the client SHALL show the corresponding empty/pending state
• AND the client SHALL not present current_package_expires_at as if it were the final calculated expiry
