feat(opencode): support light appearance for all catppuccin themes

[chrinkis]

What does this PR do?

This PR defines the light appearance for catppuccin-frappe and catppuccin-macchiato.

Catppuccin defines only one light palette, catppuccin-latte.

The light appearance of those two themes is exactly the same as the catppuccin's, so the hardoced colors were borrowed from there.

Closes #10512.

How did you verify your code works?

I tested it through bun dev.

These PRs appear to be related to appearance/theme functionality but are focused on different aspects (general appearance settings vs. specific catppuccin theme light palette support). PR #10513 is more specific to implementing light appearance for catppuccin-frappe and catppuccin-macchiato themes, so they may be complementary rather than duplicates.
