## Summary
Fixes an issue where Playwright HTML reports were not being generated
for `chromium-2x`, `chromium-0.5x`, and `mobile-chrome` test runs,
causing 404 errors when accessing report links in PR comments.
## Problem
Only the first report link (chromium) had contents - the other three
browsers returned 404 errors. Investigation revealed that artifacts for
non-chromium browsers were only uploading 1 file (report.json) instead
of the full HTML report with ~32 files.
The root cause was that these browsers run very few tests (1-6 tests
each), and when using `--reporter=html --reporter=json` together,
Playwright would only generate the JSON report without the HTML assets.
## Solution
Changed the workflow for non-chromium browsers to use the same approach
as the sharded chromium tests:
1. Run tests with `--reporter=blob`
2. Generate HTML and JSON reports separately using `merge-reports`
This ensures both HTML and JSON reports are always generated with
complete assets, regardless of test count.
## Testing
The fix can be verified by:
1. Checking that this PR's workflow run uploads similar file counts for
all browsers
2. Confirming all 4 report links are accessible and show proper HTML
content
