Fixed some bugs and optimized the data backup experience

Anniversary Timeline - Track important dates with precision: set a target date and instantly see remaining or passed days (“X Days” or “Passed”). - Auto-group memories by date into a clean, continuous timeline—browse by day with consistent typography and spacing. - Visual clarity: large day counters, readable date formats (weekday and full date), and adaptive font sizes for multi-digit durations. - Smooth scrolling and unified card styling keep long histories easy to navigate. Memories (Notes) - Capture daily moments with title, text, photos (first image preview), and optional location. - Clean presentation: per-day grouping, subtle dividers, and one-line location with icon for a compact, polished look. - Fast entry and editing designed for focus—just write, attach, and continue your day. - Integrated with tasks: attach memories to a task to enrich the timeline and context of your goals. Map Location - See your geo-tagged memories on a map; auto-focus jumps to the latest memory with valid coordinates. - Smart fallback: if no geo-tagged memories exist, centers on your current country for meaningful context. - Lightweight location formatting removes raw coordinates, showing human-friendly place names. - Ideal for visualizing where key moments happened over time. Sharing - Create a shareable image of your task card—and optionally include the latest memories—using native iOS rendering. - High-fidelity output: consistent fonts, spacing, and timeline style to match in-app design. - Share with the iOS Share Sheet to apps like Messages, Twitter, and WeChat after the image is fully generated. - Save to Photos with permission handling and clear prompts; images are rendered at a crisp resolution for posting.
