Support Album/Collection-Based Photo Import

The app currently only allows importing photos through the library view, which sorts photos chronologically by their original file date. This creates a significant usability issue when importing photos from other apps (like Keepsafe exports) that retain their original metadata dates, as these photos become scattered throughout the library and are nearly impossible to locate and select. Users need the ability to import photos from iOS's album view (Collections in iOS 16+) instead, which would enable them to efficiently select photos from "Recently Saved," "Starred," or custom albums where newly exported photos are grouped together, regardless of their original file dates.

Key points:

• Enable import from album/collection view in addition to library view

• Allow users to select photos from system albums like "Recently Saved" or "Starred"

• Support importing from custom user-created albums

• Solve the issue of chronologically-sorted photos being difficult to locate when they have old metadata dates
