Tint the chat-link preview and quoted-item icons on SIMPLEX

Sweeping the message area for the remaining secondary-role content
that read cold over the sunrise gradient — SIMPLEX secondary is a
blue (#8B99D6) and the file/link icons used the grey FileDark /
FileLight. This covers the chat-link preview card (avatar, short
description, info line) and the file / voice / chat-link icons shown
inside a quoted reply. Route them through simplexSecondaryTint() on
SIMPLEX; every other theme keeps its exact colours.
