Add address book quick-fill for frequent recipient addresses in the create-stream form

[Chuks-coderr]

Overview

Users who send streams to the same recipients repeatedly must re-enter the full Stellar address each time. An address book quick-fill in the recipient field would save time and reduce errors.

Problem

Stellar addresses are 56-character strings that are error-prone to type manually. There is no saved contacts feature in the app.

Proposed Solution

• Add a contact picker dropdown on the recipient field that appears when the user clicks a contacts icon
• Contacts sourced from the address book (localStorage) created via the existing address book CRUD UI
• Selecting a contact fills the recipient field and shows the saved alias

Acceptance Criteria

• Contacts icon on the recipient field opens the address book picker
• Selecting a contact fills the recipient field with their address
• Alias displayed alongside the address after selection
• Empty state shown when the address book has no entries
