Image history

Resolves #32 — Image History with Persistent Storage

Solution

Built a full image history system with SQLite persistence.

What was added

Image History UI

• After capturing, images are saved to disk on the ground station (data/images/)
• A "Saved Images (N)" button appears on the image panel showing count of saved images
• Clicking it reveals a scrollable thumbnail strip with all saved images
• Each thumbnail shows a user-given name (or timestamp as fallback)
• Clicking a thumbnail switches the main canvas to that image
• Red "Delete" button on each thumbnail removes it from disk and history

Image Naming

• After each capture, a popup asks the user to name the image (e.g. "center", "field-left")
• Names persist across sessions
• Skip option available if no name needed

Dot/Target Persistence

• Pixel coordinates of clicked targets are now saved to the database
• Switching away from an image and back restores all dots on the canvas
• Dots persist across page reloads and server restarts

SQLite Database (data/emu.db)
Replaced targets.json and images-meta.json with a proper SQLite database using better-sqlite3:

• targets table — 3D target points per image
• images table — saved image metadata (filename, timestamp, name)
• image_points table — pixel click coordinates per image

Existing data in targets.json and images-meta.json is auto-migrated on first server start.
