[#348] Show success message + story link after retry indexing

[realproject7]

Summary

• RecoveryBanner now shows a success state after successful retry instead of silently disappearing
• Parses tx receipt for StorylineCreated/PlotChained events to get storylineId
• Shows "View your story" link (to /story/{id}) and "Go home" link
• Stops clearing pendingIntent React state on success so banner stays mounted for feedback

Fixes #348

Files changed

• src/components/RecoveryBanner.tsx — added success state with story link
• src/hooks/usePublishIntent.ts — removed setPendingIntent(null) on success path

Test plan

• next build passes
• Retry indexing → success → banner shows "Storyline indexed successfully!" with story link
• Retry indexing → failure → banner still shows error + retry button as before

LGTM. Defensive receipt parsing with proper try/catch, success banner stays mounted with story link, removeIntent() still clears persisted state. Good UX improvement. Approved.

Verdict: APPROVE

Summary

The PR matches issue #348 and fixes the missing retry-success feedback by keeping the recovery banner mounted long enough to show a success state with navigation options. The state flow is coherent: persisted intent is cleared from storage, while the in-memory intent remains available for the banner to render post-success feedback.

Findings

• No correctness or design issues found in the submitted diff.

Decision

Approved on code review. lint-and-typecheck was still pending at the time of review, so merge should still wait for required GitHub checks.
