TYPO3 v13 compatibility, DI modernization, and new crontab:list / crontab:show commands

[stigfaerch]

Fixes #25

Summary

This branch makes the extension compatible with TYPO3 v13.4 and raises the version to 1.0.0-dev. Support for TYPO3 v11/v12 is dropped. Along the way, the codebase is modernized (native DI, typed properties, PHP 8.2+), the backend module is migrated to the v13 module APIs, and two new CLI commands are added.

Breaking changes

• Requires TYPO3 ^13.4, PHP ^8.2, and dragonmantank/cron-expression ^3.0 (previously ^2.3).
• Support for TYPO3 v11 and v12 is removed:
  • ext_tables.php (legacy module registration and v11 scheduler-module hiding) is deleted; module registration now relies solely on Configuration/Backend/Modules.php, and hiding the scheduler module solely on the BeforeModuleCreationEvent listener.
• Helhum\TYPO3\Crontab\Crontab no longer has an optional constructor argument with a makeInstance fallback: it now requires TaskRepository and ConnectionPool via DI. Code instantiating it manually must be updated.
• TaskExecutor interface gains a getArguments(): array requirement implemented by all shipped executors (Command/Scheduler/Script); custom executors must implement it.

Backend module migration to v13 APIs

• Controller uses ModuleTemplate::assignMultiple() + renderResponse() instead of the removed $this->view / setContent() / renderContent() flow.
• New Resources/Private/Layouts/Module.html replaces Default.html, rendering the doc header, flash messages, and module body the way v13 expects.
• RequireJS is replaced by ES modules: new Configuration/JavaScriptModules.php import map (@helhum/crontab/), and f:be.pageRenderer now uses includeJavaScriptModules.
• Resources/Public/JavaScript/Scheduler.js (190 lines of jQuery/RequireJS code, mostly copied from EXT:scheduler and unused here) is replaced by a small vanilla-JS ES module (scheduler.js) that only implements the per-group "check all" toggle — collapse, tooltips, and modals are handled by core/Bootstrap 5.
• List template updated to Bootstrap 5 (data-bs-* attributes, text-bg-* badges, float-end).
• ExpressionViewHelper drops the removed CompileWithRenderStatic trait in favor of a plain render() method.

Dependency injection / autowiring fixes

• Crontab service is properly autowired: it now injects ConnectionPool (Symfony DI cannot autowire Connection directly, since its constructor requires an array of params) and resolves the connection in the constructor body.
• CrontabCommand and CrontabScheduleCommand get their dependencies (Crontab, TaskRepository) via constructor injection instead of GeneralUtility::makeInstance() inside execute().

New features

• crontab:list — lists all configured tasks grouped by task group, showing identifier, executor type (Command/Scheduler/Script), title, arguments, scheduled state, and next execution time. For command tasks the title falls back to the Symfony command's own description.
• crontab:show <identifier> — shows all details for a single task (group, type, cron expression, next due/next execution, multiple-execution and retry flags, progress, executor class, and full argument list).

Other fixes and modernization

• Crontab::dueTasks() uses fetchAssociative() (the Doctrine DBAL fetch() method no longer exists).
• Implicitly nullable parameter declarations (Type $x = null) converted to explicit ?Type $x = null (deprecated as of PHP 8.4).
• SchedulerTaskRepository::$optionValues is now declared explicitly (it was previously created as a dynamic property, deprecated since PHP 8.2).
• Untyped @var-docblock properties replaced with native typed properties across commands, events, executors, task definitions, and the process manager; constructor property promotion and match() used where appropriate.
• ext_emconf.php cleaned up (removed long-obsolete uploadfolder, createDirs, clearCacheOnLoad keys); version set to 1.0.0-dev, constraint typo3 13.4.0-13.4.99.
• friendsofphp/php-cs-fixer added as dev dependency.

Testing

Running in production-mirroring TYPO3 v13.4 instances (MSP multisite platform): worker loop (crontab:execute) with idle sleep, task scheduling/removal, the backend module (list, toggle, run-immediately, terminate, delete), and the new crontab:list / crontab:show commands.
