Tile import, road map, orientation lock, CSP fix, tile error handling
- Tile import: pack_tiles.js (PNG→SQLite), Rust import_tiles + download_file
commands, JS importFromSqlite, UI in settings (file + router download)
- Road map: road_points table with 2m dedup, rebuild_roads + get_road_points
Rust commands (bypass Tauri SQL plugin 28K row limit), bike=blue walk=brown
- Orientation lock button (A/L) on recording map, hysteresis 65/35 degrees
- CSP fix: tile URL a.tile.openstreetmap.org (matches *.tile CSP pattern)
- Tile errors: done(null, tile) instead of Error to prevent crash cascade
- GPS placeholder: only show when state=waiting_gps (not on screen re-enter)
- ureq body size: use into_reader() to bypass 10MB limit for tile downloads
