Harden URL alias scripts and add eZScript verify tool

Make installer batch limits configurable via package.ini

- Read InstallerSettings.InstallBatchMaxItems from settings/package.ini in package install controller.\n- Read InstallerSettings.InstallBatchTimeBudgetSeconds from settings/package.ini in package install controller.\n- Add default values in settings/package.ini for large package imports:\n  InstallBatchMaxItems=12\n  InstallBatchTimeBudgetSeconds=6\n- Keeps adaptive batching behavior while enabling runtime tuning without editing PHP.

Harden package installer and speed up large installs

- Add defensive validation and transaction boundaries in eZPackage::installItem() to reduce partial-write corruption risk when an item fails.\n- Catch install exceptions, rollback safely, and emit explicit error context.\n- Make package install fail-fast by default and only mark package installed on full success (optional continue-on-error remains available).\n- Lift PHP execution time limits in package install controller for long-running imports.\n- Replace single-request full-loop processing with adaptive batched processing (time/item budget per request) to reduce timeout exposure and improve throughput.\n- Preserve interactive installer-step behavior while reducing redirect/bootstrap overhead for large non-interactive item sets.\n\nTested:\n- php -l kernel/classes/ezpackage.php\n- php -l kernel/package/install.php\n- cache cleared after patch to activate changes.
