Fix remaining clippy panic errors in test modules

- Add clippy::panic to allow directives in test modules for:
  - src/decoder.rs
  - src/schema.rs
  - src/types.rs

All critical clippy errors (expect_used, unwrap_used, panic) are now resolved.
Compilation successful with only non-critical warnings remaining.
