DEBtech AI Hub 1.0.2

### Fixed

• Fixed local OpenAI-compatible provider URLs when the configured base URL already ends in /v1, preventing invalid /v1/v1/... requests for model listing, connection tests, chat completions, streaming, and image generation.
• Fixed the custom admin settings form so disabled boolean options are saved correctly for API logging and budget alerts.
• Fixed provider configuration drift by adding DeepSeek and SD.cpp consistently to default provider options, settings UI, and exported add-on data.

### Verified

• Verified PHP syntax for all AI Hub PHP files.
• Verified XenForo add-on metadata, options, routes, controllers, entities, cron entries, templates, and package contents.
• Verified fresh install setup steps create the AI Hub log and budget tables with the expected schema and indexes.
• Verified release packaging includes the updated add-on data and hashes.
