fix: resolve cargo-clippy CI errors in vendor crates

- Fix rebrand issues in pezkuwi-subxt signer (sp_core -> pezsp_core,
  sp_keyring -> pezsp_keyring, sp_runtime -> pezsp_runtime)
- Fix pezkuwi-zombienet-sdk tests (subxt::PolkadotConfig ->
  pezkuwi_subxt::PezkuwiConfig)
- Correct artifact paths in subxt examples (polkadot_metadata_*.scale)
- Fix type conversion issues in subxt examples (explicit constructors
  instead of .into() for generated types)
- Add pezkuwi-subxt-utils-stripmetadata dev-dependency to metadata crate
- Use original polkadot module from external frame-decode crate
- Fix Display trait usage for generated AccountId32 types
