Implement auto-pagination iterators for all endpoints

Implementation:
- Added iter_all() method to all sync endpoints
  - PagesEndpoint.iter_all() - automatic pagination for pages
  - UsersEndpoint.iter_all() - automatic pagination for users
  - GroupsEndpoint.iter_all() - iterate over all groups
  - AssetsEndpoint.iter_all() - iterate over all assets

- Added async iter_all() to all async endpoints
  - AsyncPagesEndpoint - async generator with pagination
  - AsyncUsersEndpoint - async generator with pagination
  - AsyncGroupsEndpoint - async iterator
  - AsyncAssetsEndpoint - async iterator

Features:
- Automatic batch fetching (configurable batch size, default: 50)
- Transparent pagination - users don't manage offsets
- Memory efficient - fetches data in chunks
- Filtering support - pass through all filter parameters
- Consistent interface across all endpoints

Usage:
  # Sync iteration
  for page in client.pages.iter_all(batch_size=100):
      print(page.title)

  # Async iteration
  async for user in client.users.iter_all():
      print(user.name)

Tests:
- 7 comprehensive pagination tests
- Single batch, multiple batch, and empty result scenarios
- Both sync and async iterator testing
- All tests passing (100%)
