## Motivation
Image models (FLUX, Qwen Image) had no family grouping or quantization
metadata in the dashboard
## Changes
- Added family, quantization, base_model, and capabilities fields to all
18 image model TOML cards (FLUX.1 variants + Qwen Image variants)
- Added FLUX and Qwen Image SVG logos to FamilyLogos.svelte
- Added "flux" and "qwen-image" families to the sidebar and family sort
order
- Added "Image Gen" and "Image Edit" capability filters in
ModelFilterPopover.svelte
- Added image edit icon/badge to ModelPickerGroup.svelte
- Made the model category sidebar scrollable to accommodate the new
entries
- Hidden scrollbars on model list panels
## Why It Works
Reuses the existing family/quantization grouping infrastructure that
LLMs already use, extending it to image models with appropriate metadata
and icons
## Test Plan
### Manual Testing
Verified image models behave like text models in the model list dialog
