## Summary
Redesign the missing models warning dialog to match the MissingNodes
dialog pattern with header/content/footer separation, type badges, file
sizes, and context-sensitive actions.
## Changes
- **What**: Split `MissingModelsWarning.vue` into `MissingModelsHeader`,
`MissingModelsContent`, `MissingModelsFooter` components following the
established MissingNodes pattern. Added model type badges (VAE,
DIFFUSION, LORA, etc.), inline file sizes, total download size, custom
model warnings, and context-sensitive footer buttons (Download all /
Download available / Ok, got it). Extracted security validation into
shared `missingModelsUtils.ts`. Removed orphaned `FileDownload`,
`ElectronFileDownload`, `useDownload`, and `useCivitaiModel` files.
- **Breaking**: None
## Review Focus
- Badge styling and icon button variants for theme compatibility
- Security validation logic preserved correctly in extracted utility
- E2e test locator updates for the new dialog structure
