[Get Paid 2 23/50] Non-blocking remote recovery UX

[BullishNode]

Stack position

• Alternative Bullnym-storage stack: 23/50.
• Parent: getpaid-2-22-remote-keychain-recovery.
• Head: getpaid-2-23-remote-recovery-ux.
• This branch is independent from the existing Nostr-backed Get Paid PR stack.
• Land in numerical order with merge commits; do not squash descendants out of their recorded ancestry.

Purpose

This is part of the replacement backup transport. The wallet stores opaque, client-encrypted Keychain Manifest blobs through Bullnym and does not connect to Nostr relays for backup publication or recovery.

Included commits

• 5557872bd feat(onboarding): keep remote metadata recovery non-blocking

Diff scope

• 1 file changed, 1 insertion(+), 1 deletion(-).
• Top-level paths touched:
• lib/

Validation policy

Per the agreed stacked-PR workflow, ancestors are not built and tested in isolation. Architecture review, analyzer, focused tests, the full unit suite, UI checks, and the Android build are run cumulatively on PR 49, whose exact tree contains every ancestor.

Review notes

• Review this PR against its parent branch, not against develop, except for PR 01.
• The wallet does not use Nostr relays as a backup transport anywhere in this alternative stack.
• No remote-backup backward-compatibility layer is included because neither backup transport has shipped to users.
