RI-8268 Translate success & infinite notifications (round 2)

[valkirilov]

What

Round 2 of frontend notification translation, stacked on the round-1 error-path PR (#6125). This round localizes the success and infinite (persistent/in-progress) toasts, and aligns the whole notification namespace.

Testing

Manual — drop this dev helper into App.tsx (after the themeService calls) to
trigger every toast from the browser console, then remove it:

// App.tsx — dev-only, do not commit. Add these imports too:
//   import { addMessageNotification, addInfiniteNotification } from 'uiSrc/slices/app/notifications'
//   import successMessages from 'uiSrc/components/notifications/success-messages'
//   import { INFINITE_MESSAGES } from 'uiSrc/components/notifications/components/infinite-messages/InfiniteMessages'
//   import { stringToBuffer } from 'uiSrc/utils/formatters/bufferFormatters'
//   import { CloudJobName, CloudJobStep } from 'uiSrc/electron/constants'
//   import { store } from 'uiSrc/slices/store'
if (process.env.NODE_ENV === 'development') {
  const buf = (s: string) => stringToBuffer(s)
  const noop = () => {}

  const successArgs: Record<string, any[]> = {
    ADDED_NEW_INSTANCE: ['My Database'],
    ADDED_NEW_RDI_INSTANCE: ['My RDI Instance'],
    DELETE_INSTANCE: ['My Database'],
    DELETE_RDI_INSTANCE: ['My RDI Instance'],
    DELETE_INSTANCES: [['db-1', 'db-2', 'db-3']],
    DELETE_RDI_INSTANCES: [['rdi-1', 'rdi-2']],
    ADDED_NEW_KEY: [buf('user:1')],
    DELETED_KEY: [buf('user:1')],
    REMOVED_KEY_VALUE: [buf('myhash'), buf('field1'), 'Field'],
    REMOVED_LIST_ELEMENTS: [buf('mylist'), 3, [buf('a'), buf('b'), buf('c')]],
    INSTALLED_NEW_UPDATE: ['2.60.0', noop],
    MESSAGE_ACTION: ['1526984818136-0', 'acknowledged'],
    NO_CLAIMED_MESSAGES: [],
    CREATE_INDEX: [],
    DELETE_INDEX: ['idx:products'],
    TEST_CONNECTION: [],
    UPLOAD_DATA_BULK: [
      { summary: { processed: 100, succeed: 98, failed: 2 }, duration: 1234 },
      'commands.txt',
    ],
    DELETE_LIBRARY: ['myLibrary'],
    ADD_LIBRARY: ['myLibrary'],
    REMOVED_ALL_CAPI_KEYS: [],
    REMOVED_CAPI_KEY: ['My API Key'],
    DATABASE_ALREADY_EXISTS: [],
    SUCCESS_RESET_PIPELINE: [],
    SUCCESS_TAGS_UPDATED: [],
    AZURE_AUTH_SUCCESS: ['user@example.com'],
  }
  const testSuccess: any = (name: string) =>
    store.dispatch(
      addMessageNotification((successMessages as any)[name](...(successArgs[name] || []))),
    )
  testSuccess.keys = Object.keys(successArgs)
  testSuccess.all = () =>
    testSuccess.keys.forEach((n: string, i: number) => setTimeout(() => testSuccess(n), i * 1500))
  ;(window as any).__testSuccess = testSuccess

  const infiniteArgs: Record<string, any[]> = {
    AUTHENTICATING: [],
    PENDING_CREATE_DB: [CloudJobStep.Credentials],
    SUCCESS_CREATE_DB: [{ provider: 'AWS', region: 'us-east-1' }, noop, CloudJobName.CreateFreeDatabase],
    DATABASE_EXISTS: [noop, noop],
    DATABASE_IMPORT_FORBIDDEN: [noop],
    SUBSCRIPTION_EXISTS: [noop, noop],
    AUTO_CREATING_DATABASE: [],
    APP_UPDATE_AVAILABLE: ['2.60.0', noop],
    SUCCESS_DEPLOY_PIPELINE: [],
  }
  const testInfinite: any = (name: string) =>
    store.dispatch(
      addInfiniteNotification((INFINITE_MESSAGES as any)[name](...(infiniteArgs[name] || []))),
    )
  testInfinite.keys = Object.keys(infiniteArgs)
  testInfinite.all = () =>
    testInfinite.keys.forEach((n: string, i: number) => setTimeout(() => testInfinite(n), i * 1800))
  ;(window as any).__testInfinite = testInfinite
}

Then in the browser console:

__testSuccess.keys              // list every success factory
__testSuccess('UPLOAD_DATA_BULK')
__testSuccess.all()             // cycle all success toasts (~1.5s apart)

__testInfinite('SUCCESS_CREATE_DB')
__testInfinite.all()            // cycle all infinite toasts (~1.8s apart)

Append ?lang=bg to verify Bulgarian. (Infinite toasts are persistent — close
them between triggers, or they stack.)

Note

Low Risk
Presentation-only i18n with a small hardening change for Trans interpolation; call sites already use the new MESSAGE_ACTION signature.

Overview
This PR localizes persistent/in-progress and success toasts by replacing hardcoded English in InfiniteMessages.tsx and success-messages.tsx with i18n.t / Trans, and adds matching notification.infinite.* and notification.success.* strings in en.json and bg.json.

Rich copy (bold names, Redis Cloud / Release Notes links, inactivity notice) now uses Trans component slots instead of inline JSX. MESSAGE_ACTION takes a message id plus a typed claimed | acknowledged action so the verb can be translated separately.

escapeTrans escapes user-controlled names/ids before they go into <Trans> markup, reducing accidental HTML injection when escapeValue is off. Bulk-upload stat labels get whiteSpace: 'nowrap' for longer translated text.
