fix(Database): escape index identifiers in SQLite3 Table::dropIndexes()

 ## Bugs Fixed
 
+- **Database:** Fixed a bug where `SQLite3\Table::dropIndexes()` used single-quoted string literals instead of escaped identifiers in `DROP INDEX IF EXISTS`, causing syntax errors on index names containing quotes or special characters.
 - **Security:** Fixed a bug where `Security::__construct()` threw a `TypeError` when the CSRF cookie was an array, causing an HTTP 500 response for affected requests.
 - **Worker Mode:** Fixed a bug where every request that ended with an uncaught exception, including a `404 Page Not Found` without a 404 override, called `exit()` in the exception handler. This ended the worker script, so FrankenPHP booted a new one, and the worker loop skipped its cleanup after the request. The exception handler now returns to the worker loop.
