refactor(frontend): drop file-level eslint-disable from utils/index

- ObjectUtil.clone/deepClone become generic <T>
- cloneProps/delProps accept `object` (cast internally to AnyRecord)
- equals accepts `unknown` with proper narrowing
- ColorUtils.usageColor narrows data/threshold to `number`; total widened
  to `number | { valueOf(): number } | null | undefined` so Dayjs works
- Utils.debounce replaces `const self = this` with lexical arrow
  closure (no-this-alias clean)
- InboundList._expiryTime narrowed from `unknown` to `{ valueOf(): number } | null`
- Single-line eslint-disable remains on `Msg<T = any>` and HttpUtil
  generic defaults (idiomatic API envelope; changing default to unknown
  cascades through 34 consumer files)
