fix: Fallback to request host url when CONSOLE_API_URL is empty for O…

[04AvinashSingh]

Fixes langgenius/dify-official-plugins#3238

Summary

Self-hosted users deploying via docker-compose encounter OAuth failures (e.g., SharePoint AADSTS90102) because CONSOLE_API_URL defaults to empty, resulting in relative callback URIs being sent to the identity provider.

This PR adds a get_console_api_url() helper that gracefully falls back to request.host_url when the environment variable is blank. It updates all trigger, plugin, SSO, and tool callback generators to use this helper, ensuring absolute URLs are reliably generated right out of the box without requiring manual .env configuration.

Screenshots

N/A - Backend API fix for OAuth URL generation. No UI changes.
