DragonX compatibility: crash fixes, reorg detection, server failover, sync perf

- Fix Rust FFI panics with catch_unwind wrappers and safe CString handling
- Handle poisoned mutex/RwLock from prior panics instead of crashing
- Add stuck sync detection (10s stall threshold) and chain reorg user prompt
- Add "Skip Verification" button to seed phrase wizard
- Update payment URIs from hush: to drgx:
- Update branding strings throughout UI
- Add all 6 lite servers (lite, lite1-5.dragonx.is) with random selection
- Add server connectivity probing to skip unreachable servers
- Reuse Tokio runtime across block fetch batches to reduce sync overhead
- Update Cargo.lock dependencies
