Add a key deprecation notice and redeem button on the portfolio page for deprecated keys

[Chucks1093]

Summary

When a creator deprecates their key, holders need to know and be able to redeem their keys for the fixed buyback price. A deprecation notice on the portfolio holding row and a Redeem button that submits the redeem contract call would make this action discoverable.

Scope

• Detect deprecated keys by checking status === 'Deprecated' on each holding row
• Show an amber deprecation banner on the holding row: 'This key has been deprecated. Redeem your keys for [buybackPrice] XLM each.'
• Add a Redeem All button that submits the redeem contract call with the full holding quantity
• Show the total XLM to be received in the redeem confirmation modal
• Remove the holding row after a successful redemption and show a success toast with the total received

Acceptance Criteria

• Deprecation banner shown on deprecated holding rows
• Buyback price per key and total XLM shown correctly
• Redeem All submits the correct quantity to the contract
• Success toast shows total XLM received after redemption
• Holding row removed from portfolio list after redemption

ETA: 12 hours
