App and Website were always shown together already, so giving them
separate tabs implied a toggle that didn't exist -- merged into one
"App & Website" tab. The Email tab now shows a real, colour-bound
sample (plain header with a secondary-coloured crest badge, a
primary-coloured button) matching the actual branded emails this app
already sends -- audited every mail-sending call site (claims.py,
the new invoicing service, and platform billing's club-facing
reminders) and the first two already use the branded shell; billing's
is intentionally unbranded since it's RosterChief invoicing the club,
not the club invoicing its own members.
