feat(supporters): merge hand-maintained supporters, rank by amount

Add a MANUAL_SUPPORTERS list in patreon.rs for donations that arrive
outside Patreon; both the native and web boot paths merge it with the
fetched patrons and sort the combined list by amount (highest first,
then alphabetically). This also sorts the web supporters list, which
previously arrived unordered, and keeps hand-maintained supporters
visible when the Patreon fetch returns nothing (offline / no token).
