[Fix] Trash icon is hidden in dark mode environment dropdown

What changed

The delete action in the homepage environment dropdown now explicitly uses black against the selected lime row, while retaining its destructive color when the action itself is hovered.

Why this change was made

The previous muted and accent foreground treatments did not reliably override the dropdown and ghost-button styling in dark mode, leaving the trash glyph low-contrast or invisible.

Impact

Admins can clearly see both environment actions when hovering a selected environment in dark mode. The change is limited to the trash icon's foreground colors; its interaction remains unchanged.

No new code issues found. See task

• apps/web/src/components/tasks/SelectEnvironmentOrRepository.tsx:431 uses the same accent token as the selected row background, so the trash icon remains low-contrast in dark mode.

Fixed the dark-mode selected-row contrast in 7767740. The trash action now explicitly overrides both the dropdown SVG color and ghost-button hover color; visual proof confirms both action glyphs are visible against the lime row.
