De-fork POS chrome/assets and import CRM products only

Finish removing the upstream platform fork: drop the Hosting/SSL/Domain
notification classes + their mail views, the email/mailbox/domains/hosting
view trees, the Mini/Afia/search/paystack partials and unused components, and
the now-orphan support helpers (DomainConfig, MailboxPricing,
ResellerClubLegacy), SmsService, and fork configs (afia, hosting, domain,
email, mailbox, qr, mail_brands, notifications, ...). Reparent the
notifications page off the hosting layout onto the POS app layout (it had
referenced undefined hosting./mini. routes). Computed the removable set from a
reachability scan of the POS view graph; kept views reference no removed
routes/services.

Branding: favicon now uses the updated favicon.ico (favicon.svg removed);
signed-out fallback logo points at the POS logo.

CRM import: constrain the catalogue pull to type=product so CRM services are
never imported as POS products (server-side filter + defensive client skip).

Test suite green (8 passed, 29 assertions); all routes resolve and every
remaining Blade compiles.
