fix: use brand color for error toast

[jvsena42]

Fixes #1009

This PR switches the .error toast color from the crimson red accent to the brand orange so it matches the design prototype.

Description

The error toast type previously used the red accent (#E95164), a crimson that does not appear in the prototype. The prototype's failure toasts ("Spending Balance Setup Failed", "Instant Payments Unavailable") all use the brand orange (#FF4400), so error toasts now use the brand color too.

The separate warning toast branch is intentionally left in place even though it currently resolves to the same brand color, so a distinct color can be reintroduced for errors in the future without reworking the mapping.

Design reference: Figma prototype

Greptile Summary

This PR fixes the error toast color by changing it from Colors.Red (#E95164) to Colors.Brand (#FF4400) to match the Figma design prototype. A changelog fragment for issue #1009 is also added.

• ToastView.kt: The tintColor() mapping for Toast.ToastType.ERROR is updated from Colors.Red to Colors.Brand; WARNING already mapped to Colors.Brand, so both types now share the same color — the PR notes this is intentional.
• changelog.d/next/1009.fixed.md: A one-line changelog entry is added describing the fix.

Confidence Score: 5/5

Safe to merge — the change is a one-line color swap in a single composable function with no logic impact.

The only changed behavior is the toast tint color for ERROR toasts. The mapping is trivially correct and the rest of the component is untouched. The one observation — that WARNING and ERROR now share the same color — is acknowledged and intentional per the PR description.

No files require special attention.
