1u64 << (prefix_len * 4) overflows once prefix_len is 16 or more, so transfers hash-address --prefix-len 64 panics in a debug build and query shows a wrong ratio in release. it now prints 2^N past u64, shorter prefixes print the same as before

APPROVE — no blocking findings.

Reviewed head a91abfb59a8aa3fcabaf7e6e65b84931f61fdbef against base a74fd735fdb7cae2381b66dbaaa513630c0d58d9.

Both transfers query and transfers hash-address now share the overflow-safe formatter. Decimal output is preserved for prefixes below 16 hex characters, and longer prefixes correctly use powers of two, including 2^256 for length 64. The regression tests cover the 15/16 boundary and full-length command handling.

Validation:

• cargo test --locked --lib cli::transfers::tests: 4 passed.
• cargo +nightly-2026-08-31 fmt --all -- --check: passed.
• git diff --check against the recorded base: passed.
• GitHub format, Clippy/docs, security audit, and dependency cooldown checks passed. Build/test matrix and examples jobs were still running at review time.
