fix: resolve merge conflicts and compile errors for transport layer

- Resolve stash conflicts in Cargo.toml, rpc/mod.rs, AppDetails.vue, Apps.vue
- Fix ScopedIp conversion in LAN transport (mdns-sd compatibility)
- Fix String vs &str in transport RPC send handler
- Remove duplicate mod transport declaration
- Remove stale mesh.discover route (replaced by mesh.peers/messages/send)
