Summary

New prices namespace export on balance.service.ts
Local rate-limit (1 request / 2s), in-flight dedup, exponential backoff (2/4/8s, max 3 retries on 5xx-class errors), no retry on 401/403/404/429, hard 100/session cap
Annexe B i18n mapping wired (PriceError → balance.priceFetching.errors.* keys)
9 vitest tests with vi.useFakeTimers() — happy, auth/premium/404 no-retry, 429 no-retry, 5xx retries, dedup, pacing, session cap

Test plan

npx tsc --noEmit clean
npx vitest run src/services/balance.service.test.ts — 94/94 green (existing 85 + 9 new)
No external test libs — only vi.fn() on invoke

Depends on Rust side from #155 PR (string-based invoke; this PR works in isolation against mocked invoke).

Closes #156

- prices.fetchPrice wraps invoke('fetch_price', ...) with local rate-limit (1/2s), in-flight dedup, exp backoff on 5xx (2/4/8s, max 3 retries), no retry on 4xx/429, hard 100/session cap
- 9 vitest tests with vi.useFakeTimers() (happy, 401/403/404, 429 no-retry, 5xx retries, dedup, pacing, session cap)
- Annexe B i18n mapping wired (PriceError → balance.priceFetching.errors.* keys)
- Session cap checked before rate-limit/dedup; failures do not consume budget (MEDIUM decision)

Closes #156
