refactor: remove additional dead exports and unused actions

Remove buildFontUrl, measureText, uncached, invalidateCache, fetchJsonWithFlareSolver, upsertPermission, deletePermission, bulkImportPermissions, clearAllPermissions, bulkDeletePermissions, bulkDeletePhotos, userReplyTicket, closeTicketByUser. Update staff-smoke-contract test for bulkDeletePhotos removal.
