feat: add per-view data refresh controls (manual + auto)

[Joeltabe]

Motivation

• Provide users manual and automatic refresh controls for real-time views so data can be explicitly refreshed or polled with configurable intervals and scope.
• Surface feedback (last-updated timestamp, progress animation, cancel) and support refresh-on-focus to keep dashboards up-to-date without global, hard-coded polling.
• Persist preferences per view so users keep their chosen refresh behavior across reloads and sessions.

Description

• Add a new hook useRefreshControls to persist per-view preferences (localStorage), manage selected refresh targets, run manual refreshes (via query refetch or provided refetch functions), schedule auto-refresh intervals, support refresh-on-focus, and allow cancellation via React Query.
• Add reusable UI under frontend/src/components/RefreshControls/ (RefreshButton, AutoRefreshToggle, RefreshSettingsPanel, and an index.tsx wrapper) that shows refresh animation, last-updated timestamp, interval selection, refresh scope (all vs selective), and cancel action.
• Integrate the controls into Dashboard, Analytics, Bridges, Transactions, and Asset Detail pages and wire targets to each page’s queries; update TransactionHistory to accept refreshInterval and refreshOnWindowFocus props.
• Update data hooks (useAssets, useAssetsWithHealth, useBridges, usePrices, useTransactions) to accept refresh options (refetchInterval, refetchOnWindowFocus) so the UI controls drive polling behavior; document persistence keys and behavior in README.md.
• Update tests to provide a QueryClientProvider and mock refetch where needed.
• Closes Create Asset Metadata Management StellaBridge/Bridge-Watch#117

Testing

• Ran unit tests with npm run test --workspace=frontend and all frontend tests passed (2 tests total).
• Ran linter with npm run lint --workspace=frontend and linting completed successfully.
• Attempted npm run build:frontend which failed due to pre-existing TypeScript errors (unused React imports in skeleton components) unrelated to these changes; tests and linting succeeded despite the build issue.
