Integrate encrypted in-app wallet vaults

[jwahdatehagh]

Summary

Replaces the plaintext in-app wallet setup in Components/Layers with the encrypted keyring from @1001-digital/wagmi-in-app-wallet.

• adds create, restore, unlock, backup, passkey, passphrase-change, and explicit lock flows
• adds an on-demand unlock dialog used by the Wagmi connector
• introduces a host-configurable WalletVaultStore for authenticated API sync
• supplies an encrypted local fallback for hosts without remote storage
• locks and reloads when the host session identity changes
• never reads or automatically migrates the legacy plaintext key
• adds coordinated major changesets for components.evm and layers.evm

Dependency chain

1. Wallet primitive: Add encrypted, syncable in-app wallet vaults wagmi-in-app-wallet#1
2. This Layers integration
3. Networked product flow: https://github.com/networked-art/monorepo/pull/27

The wallet package must be published before the Layers major is released. Networked can then update its dependency to the published Layers version.

Validation

• pnpm --filter @1001-digital/layers.evm typecheck
• git diff --check

The repository-wide typecheck still has unrelated pre-existing layers.base import/dependency failures; the changed EVM layer passes.
