v2.0.7 — oumta-dashboard: timeline overhaul

Two-column timestrahl layout + workload quick-filter.

- Left column (64px): date badge (big day / small month e.g. 18 APR)
  shown only on the first cluster of each day, coloured dot, and a
  compact HH:MM time (or "just now" when <60s old).
- Dot colour = dominant severity of the cluster
  (error > warning > recovered > image > info).
- Events within a 60s tolerance window collapse into one entry so
  simultaneous rollouts of multiple deployments appear as a single
  dot with each sub-event listed in the right column.
- Workload quick-pick pills above the timeline. "all" + up to six
  inline pills (workloads sorted by recency); the rest collapses into
  a "+N more" dropdown. Clicking a workload name inline inside an
  event also applies the filter. Filter hides itself when the view is
  scoped to a single workload (opened via the overview attention list).
