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
style: format code and apply clippy lint fixes
