feat(rewards): show ondo outcome toasts

[VGR-GIT]

Description

Shows a toast on the rewards home page or the campaign overview page if you're a potential winner with a verification code, or if you're a participant and we know that you're not a winner.

Changelog

CHANGELOG entry: null

Screenshots/Recordings

Showing toast for participant who didn't win once we know in the same tier for sure that there are 5 winners:

Showing a toast for winners with verification code but still in pending state.

• Dimissing the toast will cause it to not show up anymore in same session or cross session.
• For non winners, it takes users to ondo details page;
• For winners with verification code but pending, it takes them to winner sheet.

Note

Medium Risk
Adds a new focus-driven toast + navigation side effect on key Rewards screens and persists new dismissal state in Redux, which could impact user-facing UX and state rehydration if mis-keyed or triggered unexpectedly.

Overview
Adds useOndoOutcomeToast, which detects the most recently completed ONDO Holding campaign, derives an outcome variant from participant outcome data, and shows a persistent icon toast (with haptics) that deep-links to the winning or campaign details view.

Introduces Redux support for remembering dismissed outcome toasts via dismissedCampaignOutcomeToasts (new selector + dismissCampaignOutcomeToast action) and persists/rehydrates this map.

Wires the hook into RewardsDashboard and CampaignsView, updates fixtures/locales, and adds/extends unit tests covering toast behavior, dismissal, and integration.

E2E Test Selection:
The changes in this PR are scoped to the Rewards feature (Ondo campaign outcome toasts):

1. New hook useOndoOutcomeToast.ts: Adds toast notification logic for Ondo campaign outcomes. This is self-contained within the Rewards module and doesn't affect shared components like navigation, confirmations, or browser.

2. CampaignsView.tsx & RewardsDashboard.tsx: Minimal changes — just calling the new hook. No structural changes to these views.

3. Redux reducer changes: Added dismissedCampaignOutcomeToasts state field with a new action and rehydration support. This is additive and backward-compatible.

4. default-fixture.json (CRITICAL): Added dismissedCampaignOutcomeToasts: {} to match the new Redux state shape. This is a purely additive change — it initializes a new empty object field that existing tests don't reference. No existing E2E tests will break because of this.

5. locales/languages/en.json: New i18n strings for toast variants — no impact on existing tests.

No E2E test tags are applicable because:

• There are no E2E tests covering the Rewards/Campaigns feature in the available test suite
• The default-fixture.json change is backward-compatible and won't break any existing tests
• The changes don't touch shared components (TabBar, Browser, Confirmations, AccountSelector, etc.) that could cause regressions in other test areas
• None of the available tags (SmokeCard, SmokePerps, SmokePredictions, SmokeWalletPlatform, etc.) cover Rewards campaign toast functionality

Performance Test Selection:
No performance-sensitive code paths are affected. The changes add a new hook with Redux selectors and toast display logic, but this is not in any critical rendering path (no list rendering, no startup code, no account/network selectors). The new state field is an empty object that won't impact any performance metrics.
