fix: resolve clippy warnings for Rust 1.93

- Replace manual modulo checks with .is_multiple_of()
- Use enumerate() instead of manual loop counters
- Use iterator .take() instead of index-based loops
- Use slice literals instead of unnecessary vec![]
- Allow too_many_arguments in IBC and bridge crates (protocol requirements)
- Allow assertions on constants in integration tests
