Delete cw_zano / cw_tron / cw_solana / cw_decred packages + all references

These chains were already disabled in availableWalletTypes (none of them
were getting created), but the source dirs and the codegen scaffolding
for them still lived in tree (~20K lines of dead Dart).

Surgery:
- Delete cw_decred/ cw_solana/ cw_tron/ cw_zano/ source trees
- Strip 5 generate*() function bodies from tool/configure.dart
  (generateSolana, generateTron, generateZano, generateDecred,
  generateZcash) plus their top-level imports, args, calls,
  signatures, and conditional pubspec/walletTypes injection blocks.
  configure.dart shrinks from 2134 to 1561 lines and dart analyze
  is clean.
- Strip solana/tron secrets config + output paths from
  tool/import_secrets_config.dart
- Delete scripts/{android,ios,macos}/build_decred.sh,
  scripts/ios/build_zano{,_all}.sh
- Patch scripts/{android,ios,macos}/build_all.sh,
  scripts/android/copy_monero_deps.sh, scripts/ios/setup.sh,
  scripts/ios/gen_framework.sh to drop decred/zano steps
- Patch scripts/android/docker/build.sh + Dockerfile.final to drop the
  decred Docker stage; delete scripts/android/docker/Dockerfile.decred
- Update .github/workflows/build-linux.yml comments to reflect the
  remaining cw_* module list (evm, nano, bitcoin)

Note: WalletType.{solana,tron,zano,decred,zcash} enum values still live
in cw_core/lib/wallet_type.dart and there are dead switch cases in
lib/di.dart and lib/new-ui/pages/*.dart that reference them. Those
paths are unreachable (the enum values never get assigned to any wallet)
but cleaning them up is a separate hygiene pass.
