fix: resolve all fmt and clippy warnings

Main lib (src/):
- Add #[allow(dead_code)] for build_info field (stored to prevent Prometheus unregistration)
- Add #[allow(dead_code)] for first_seen field (reserved for future rate limiting)
- Replace .or_insert_with(RelaySyncNeeds::default) with .or_default()
- Replace manual div_ceil implementations with .div_ceil(100)

Test code (tests/):
- Replace .expect(&format!(...)) with .unwrap_or_else(|_| panic!(...))
- Remove needless borrows in fetch_metrics() calls
- Add #[allow(dead_code)] and #[allow(unused_imports)] to test helpers module

grasp-audit:
- Apply cargo fmt to fix formatting
