fix: validation script now completes all 6 checks successfully

Fixed issue where validate-modules.sh would exit prematurely during check 3
due to grep failures in while loops with set -e enabled.

Changes:
- Added set -o pipefail for better error handling
- Temporarily disable set -e during grep checks in view file validation loop
- Script now completes all 6 validation checks successfully
- Exit code 0 when only warnings present (debug files without menu entries)

Validation results:
✓ Check 1: RPCD naming vs ubus objects (15 modules)
✓ Check 2: Menu paths vs view files (15 modules, 100+ views)
✓ Check 3: View files have menu entries (2 warnings for debug files)
✓ Check 4: RPCD permissions (15 scripts executable)
✓ Check 5: JSON syntax validation (30 files)
✓ Check 6: ubus naming convention (17 objects)
