feat: per-category enable/disable for admin notifications

Add ADMIN_NOTIFICATIONS_{CATEGORY}_ENABLED settings (default True) for
all 10 notification categories: purchases, renewals, trials, balance,
addons, infrastructure, errors, promo, partners, tickets.

Setting ADMIN_NOTIFICATIONS_PROMO_ENABLED=false now completely suppresses
promo notifications (promocode activations, campaign visits, promo group
changes) instead of silently falling back to the general topic.

Also fix referral_contest_service direct bot.send_message bypass —
now respects ADMIN_NOTIFICATIONS_PROMO_ENABLED setting.
