Release 4.232.0

ov-metrics.js: the network's one way to show numbers (ai-metrics.md). Report, Exchange, Compare and the admin panel draw their AI and usage numbers with it, and nobody draws a chart of their own. The look is the theme's (tokens only). Every piece works at 390 px and in both themes, and stays still with motion off.

• OVMetrics.tiles(): label, value, unit, a delta that knows whether up is good, a sub-line and a trend.
• .spark(): a trend line with its last point.
• .bars(): a ranked bar list.
• .percentiles(): p50, p90 and p95 on one scale, with a spoken summary.
• .split(): one bar in parts, with a legend.
• .table(): sortable on a click, with aria-sort, numeric columns and an optional in-cell bar.
• OVMetrics.format: the same words everywhere, and servers get them from require('openvibe-shared/ov-metrics'):
  • ms (540 ms · 1.3 s · 1 min 38 s), usd ($0.0042 · $61.20), count (18k · 9.1M), tokens, rate (99.4%);
  • tps (86.0 tok/s), bytes, delta (+12%);
  • unknown is a dash, never 0.
• Test ov-metrics-chrome.
