fix(browser): improve storage state persistence in CDP strategy

Enhance storage state persistence mechanism in CDP browser strategy by:
- Explicitly saving storage state for each browser context
- Using proper file path for storage state
- Removing unnecessary sleep delay

Also includes test improvements:
- Simplified test configurations in playwright tests
- Temporarily disabled some CDP tests
