Give Requests its own colour instead of leaving 4 fastext entries plain

Plain ink for Watch/Requests/Activity/Settings read as flat and
unfinished, not deliberate — user feedback: "the new colors are
awful and basically the same color." Requests gets magenta
(--pending) back: not an arbitrary reuse, it's the same colour a
request already carries once approved elsewhere in the app, and
Requests genuinely is "waiting on a human." That's the real ceiling
though — the locked eight teletext colours leave exactly five legible
as text on black (blue fails contrast, black is invisible on black),
so Watch/Activity/Settings still share plain ink rather than a sixth
colour that doesn't exist in this palette.
