Fix/max tokens hardcoded

[n-iv]

We noticed some occurrences of 'max_tokens' => 1000 in the Nextcloud codebase, specifically in:

• apps/integration_openai/lib/TaskProcessing/TextToTextProvider.php
• apps/integration_openai/lib/TaskProcessing/HeadlineProvider.php
• apps/integration_openai/lib/TaskProcessing/TopicsProvider.php

This prevents requests from being executed in full, and leads to half-generated documents or truncated answers, which ruins the user experience.

We replaced those faulty lines with:
'max_tokens' => $this->openAiSettingsService->getMaxTokens()

Pull request overview

This PR removes hardcoded max_tokens => 1000 defaults in the task-processing providers and instead uses the configured value from OpenAiSettingsService, preventing truncated generations when admins have configured higher token limits.

Changes:

• Replaced hardcoded max_tokens defaults with $this->openAiSettingsService->getMaxTokens() in task optional input defaults.
• Applies the same configuration-driven behavior consistently across headline, topics, and general text-to-text providers.
