[Issue]: Vectorize button does not perform embedding vectorization #4844

Description

@SpicyMarinara

Summary

The Vectorize button appears to do nothing in v2.4.2. The issue occurs with different connections and a local embedding model, and another user reproduced it with OpenRouter.

Expected behavior

Selecting Vectorize should run embedding vectorization or display an actionable error when the configured provider cannot process the request.

Actual behavior

Clicking Vectorize produces no visible result or warning. An OpenRouter configuration with a potentially unfunded API key also did not display an insufficient-funds warning.

Steps to reproduce

  1. Configure an embedding connection or local embedding model.
  2. Attempt to start embedding vectorization using the Vectorize button.
  3. Observe that no visible action, result, or error message appears.
  4. Repeat with different connections or an OpenRouter API key.

Environment

  • Marinara Engine version: v2.4.2 (build d7925d9 reported by one reproducing user)
  • Install type: Not provided
  • OS + version: Windows 10 reported by the original user; not provided for the second user
  • Browser or app shell: Not provided

Additional context

The original user tested different connections and a local embedding model with the same result. A second user reproduced the behavior, but noted that their OpenRouter API key might not have available funds.

:MonkaSweat: This could just be because I don't have any money against my OpenRouter API key, but otherwise I can repro... it isn't warning me about lack of money in the API key
