refactor(beszel): remove dead exports and deduplicate formatters

- Remove unused getBandwidthRates, getContainerNetworkRate, formatMB
- Remove unused alertColorMap from colors.ts
- Remove duplicate chartAxisFormatters.percentPrecise (identical to .percent)
- Make chartAxisFormatters.percent reference formatPercent directly
