refactor: convert partner/withdrawal modals to separate pages

Replace 7 modal dialogs with 8 dedicated page routes for better
mobile/Telegram WebApp UX. Add campaign management (assign/create
with auto-assign) to partner detail page.

New pages: AdminApplicationReview, AdminPartnerCommission,
AdminPartnerRevoke, AdminWithdrawalReject, AdminPartnerCampaignAssign,
AdminPartnerCampaignCreate, ReferralPartnerApply,
ReferralWithdrawalRequest.

~610 lines removed from parent pages, ~425 lines removed net.
