Christian Byrne 3b4811b00d feat: deploy E2E coverage HTML report to GitHub Pages (#11291) ...

## Summary

Browsable E2E coverage report deployed to GitHub Pages on every main
merge, replacing the current workflow of downloading LCOV artifacts and
using an external viewer.

## Changes

- **What**: After merging shard LCOVs, run `genhtml` to produce an HTML
report with per-file line coverage. On `main`, deploy to GitHub Pages
via `actions/deploy-pages`. For PR runs, the HTML report is still
available as the `e2e-coverage-html` artifact.
- **Dependencies**: None new — `genhtml` is part of the `lcov` package
already installed in the workflow.

## Review Focus

- **GitHub Pages must be enabled**: Settings → Pages → Source → "GitHub
Actions". Without this the deploy job will fail silently.
- The deploy job only runs for `main` branch (`if:
github.event.workflow_run.head_branch == 'main'`) so PR coverage doesn't
clobber the deployed report.
- Added `pages: write` and `id-token: write` permissions to the workflow
for the Pages deployment.
