feat: blockchain rescan via daemon restart + status bar progress

- Fix z_importwallet to use full path instead of filename only
- Add rescanBlockchain() method that restarts daemon with -rescan flag
- Track rescan progress via daemon output parsing and getrescaninfo RPC
- Display rescan progress in status bar with animated indicator when starting
- Improve dark theme card contrast: lighter surface-variant, tinted borders, stronger rim-light
