Pratik Mankawde 62ef753804 feat(telemetry): split perf-run annotations by load driver ...

A single "Annotate perf-iac runs" layer matched only `perf-iac`, so a Locust
load window was indistinguishable from a JMeter one. perf-iac now tags every
region with its load driver, so each driver can have its own layer and colour.

- Replace that layer with `Perf Runs (JMeter)` and `Perf Runs (Locust)`, each
  matching ["perf-iac", "<driver>"] with matchAny:false, on 12 dashboards.
- job-queue, ledger-data-sync and log-derived-insights had an empty annotations
  list and drew no perf regions at all; they now carry the builtIn layer plus
  both driver layers.
- Grafana tag matching is a superset AND with no negation, so a generic
  `perf-iac` layer also matches every driver region. Keeping one alongside the
  driver layers would draw each load window twice, so it is replaced, not kept.
- Document the layers in the telemetry runbook, including two rendering limits:
  annotations draw only on timeseries, state-timeline and candlestick panels,
  and the shaded fill is 10% opacity so the region edges carry the colour.
- Add `jmeter` to the cspell dictionary; the hook rejects the bare word.
