Remove Trivy workflows + Fix YAML syntax errors

Trivy Removal:
- Remove entire docker-security-scan job from security workflow
- Remove Trivy vulnerability scanner from release workflow
- Remove Trivy filesystem scan and related steps
- Update security summary to reflect Trivy removal
- Eliminates GitHub API authentication issues

 YAML Syntax Fixes:
- Fix indentation errors in ci.yml (line 31)
- Fix indentation errors in docs.yml (line 30)
- Correct 'with:' block alignment with 'uses:' statements
- Fix token parameter indentation (8 spaces standard)
- Applied across all workflow files consistently

 Result:
- All workflows now have valid YAML syntax
- No more Trivy-related GitHub API calls
- Cleaner, simpler security workflow
- Workflows ready for successful execution
