Description

Summary

Migrates selected Identity + Multichain Accounts coverage from E2E toward Component View tests for the E2E -> CV effort.

This PR adds shared CV identity and multichain-account presets/renderers, plus route-probe and controller mock support, then adds CV coverage for:

• Backup & Sync account/contact sync settings toggles
• Contacts list/form behavior: opening the add form, editing an existing contact, duplicate-address validation, saving a valid contact through AddressBookController, and opening the network selector
• Multichain account selector behavior: account creation per SRP section, account selection, external-address search/selection, invalid-address handling, keyboard toggling, search filtering/empty state, and multi-SRP display
• Account group details behavior: account rename/edit validation, route wiring to address list/private keys/account actions, and multi-SRP details display
• Multichain accounts intro and learn-more modal navigation
• Multichain permissions summary actions/state
• Private key list password, reveal, and copy behavior
• Delete account sheet behavior: imported account delete confirmation, cancel, failure handling, and HD-account non-removal guard

E2E removal

Removes:

• tests/smoke/multichain-accounts/account-details.spec.ts

Rationale: the active Account Details rename behavior from that smoke spec is now covered directly at the CV layer through route wiring, validation, and controller interaction.

Manual testing steps

Feature: Identity + Multichain Accounts CV migration

  Scenario: verify migrated CV coverage
    Given the Identity + Multichain Accounts CV migration branch is checked out

    When yarn jest -c jest.config.view.js app/components/Views/Settings/Identity/BackupAndSyncSettings.view.test.tsx app/components/Views/Settings/Contacts/Contacts.view.test.tsx app/component-library/components-temp/MultichainAccounts/MultichainAccountSelectorList/MultichainAccountSelectorList.view.test.tsx app/components/Views/MultichainAccounts/AccountGroupDetails/AccountGroupDetails.view.test.tsx app/components/Views/MultichainAccounts/sheets/DeleteAccount/DeleteAccount.view.test.tsx app/components/Views/MultichainAccounts/IntroModal/MultichainAccountsIntroModal.view.test.tsx app/components/Views/MultichainAccounts/PrivateKeyList/PrivateKeyList.view.test.tsx app/components/Views/MultichainAccounts/MultichainPermissionsSummary/MultichainPermissionsSummary.view.test.tsx --runInBand --silent --coverage=false is run
    Then all 8 CV suites pass with 70 tests passing

Validation performed locally:

• yarn jest -c jest.config.view.js app/components/Views/Settings/Identity/BackupAndSyncSettings.view.test.tsx app/components/Views/Settings/Contacts/Contacts.view.test.tsx app/component-library/components-temp/MultichainAccounts/MultichainAccountSelectorList/MultichainAccountSelectorList.view.test.tsx app/components/Views/MultichainAccounts/AccountGroupDetails/AccountGroupDetails.view.test.tsx app/components/Views/MultichainAccounts/sheets/DeleteAccount/DeleteAccount.view.test.tsx app/components/Views/MultichainAccounts/IntroModal/MultichainAccountsIntroModal.view.test.tsx app/components/Views/MultichainAccounts/PrivateKeyList/PrivateKeyList.view.test.tsx app/components/Views/MultichainAccounts/MultichainPermissionsSummary/MultichainPermissionsSummary.view.test.tsx --runInBand --silent --coverage=false - PASS, 8 suites / 70 tests
