chore(lint): extend low-risk clippy cleanup batch

- normalize numeric literals (115_200) in hardware/peripheral config paths

- remove test-only useless format! allocations in discord IDs

- simplify closures and auto-deref in browser/http/rag/peripherals

- keep behavior unchanged while reducing warning surface
