feat(usage): enhance dashboard with auto-refresh control and robust formatting

- Add configurable auto-refresh interval toggle (off/5s/10s/30s/60s) to usage dashboard
- Extract shared format utilities (fmtUsd, fmtInt, parseFiniteNumber, getLocaleFromLanguage)
- Refactor request log time filtering to rolling vs fixed mode with validation
- Use stable serializable query keys instead of filter objects
- Handle NaN/Infinity safely in number formatting across all usage components
- Use RFC 3339 date format in backend trend data
