lif 4ed43c2a32 fix: Improve image captcha contrast for dark mode (#36265) ...

## Summary
This PR fixes #36255

The image captcha was using random colors which often resulted in poor
contrast against dark backgrounds, making it difficult or impossible for
users to read in dark mode.

## Changes
- Added a custom color palette to the image captcha configuration in
`services/context/captcha.go`
- The palette uses high-contrast colors (bright red, blue, green,
yellow, purple, and dark blue-gray) that provide good visibility in both
light and dark themes
- This improves accessibility and user experience without changing any
existing functionality

## Testing
- Builds successfully
- All existing tests pass
- The color palette is properly supported by the upstream
`gitea.com/go-chi/captcha` library
