feat: explain empty AI CoC page views and add per-tab deep links

[dosteinacher]

Why

Two things on the claps analytics dashboard:

1. Empty AI CoC page views looked like a bug. Session write-ups under /en/aicoc/ get very little direct web traffic, so they almost never surface in the heavily sampled AEM RUM data (the whole site currently reports only a few hundred weighted views). The result was a bare — in the Page views column and KPI, with no explanation — indistinguishable from an error or from missing live attendance.
2. No way to share a direct link to a specific tab. Only the top-level dashboard URL existed; the Blog and AI CoC views couldn't be linked separately.

What changed

• Explanatory hint instead of a bare —:
  • Persistent note under the AI CoC table explaining page views come from (sampled) RUM and that — means no sampled traffic, not an error — and that it's separate from live attendance.
  • Tooltips on the empty per-session cells and the "Session Page Views" KPI card that distinguish "RUM not loaded yet" from "loaded, but no sampled traffic".
• Per-tab deep links: the active tab is reflected in the URL hash and applied on load:
  • Blog — …/admin/claps-analytics.html#blog
  • AI CoC Sessions — …/admin/claps-analytics.html#aicoc

Testing

Verified locally: #aicoc / #blog open the correct tab on load, tab clicks update the URL hash, and the hint text renders. No behavior change for the blog metrics.
