Remove overly complex verification logic that was causing all browser
jobs to fail. Browser installation should fail fast and clearly if
there are issues.
Changes:
- Remove multi-line verification scripts from all 3 browser install steps
- Simplify to single command: npx playwright install --with-deps {browser}
- Let install step show actual errors if it fails
- Let test execution show "browser not found" errors if install incomplete
Rationale:
- Previous complex verification (using grep/find) was the failure point
- Simpler approach provides clearer error messages for debugging
- Tests themselves will fail clearly if browsers aren't available
Expected outcome:
- Install steps show actual error messages if they fail
- If install succeeds, tests execute normally
- If install "succeeds" but browser is missing, test step shows clear error
Timeout remains at 45 minutes (accommodates 10-15 min install + execution)
