feat: Add pagination support for media assets history (#6373)

## Summary
- Implement pagination for media assets history to handle large datasets
efficiently
- Add infinite scroll support with approach-end event handler  
- Support offset parameter in history API for both V1 and V2 endpoints

## Changes
- Add offset parameter support to `api.getHistory()` method
- Update history fetchers (V1/V2) to include offset in API requests
- Implement `loadMoreHistory()` in assetsStore with pagination state
management
- Add `loadMore`, `hasMore`, and `isLoadingMore` to IAssetsProvider
interface
- Add approach-end handler in AssetsSidebarTab for infinite scroll
- Set BATCH_SIZE to 200 for efficient loading

## Implementation Improvements
Simplified offset-based pagination by removing unnecessary
reconciliation logic:
- Remove `reconcileHistory`, `taskItemsMap`, `lastKnownQueueIndex`
(offset is sufficient)
- Replace `assetItemsByPromptId` Map → `loadedIds` Set (store IDs only)
- Replace `findInsertionIndex` binary search → push + sort (faster for
batch operations)
- Replace `loadingPromise` → `isLoadingMore` boolean (simpler state
management)
- Fix memory leak by cleaning up Set together with array slice

## Test Plan
- [x] TypeScript compilation passes
- [x] ESLint and Prettier formatting applied
- [x] Test infinite scroll in media assets tab
- [x] Verify network requests include correct offset parameter
- [x] Confirm no duplicate items when loading more
