Events deposit-report access and fixed export fields

For GiveCampus reporting.

Events deposit reports are included in Superadmin, Fundraising Superadmin, Events Superadmin, Events Finance Admin, and Events Reporting Admin. Gift Management Admin alone does not include Events deposit-report access. An administrator who manages Events staff should assign an appropriate Events role; partners cannot add an individual deposit-report permission within another role. The standard Event Registration Deposit Report uses fixed columns and has no separate transaction-fee or donor-covered-fee column. Its payment amount should not be relabeled as net proceeds. Custom reports are a separate feature and only expose their supported fields.
