Introduce Invoke-ListMailboxForwarding HTTP entrypoint and Get-CIPPMailboxForwardingReport report function. The entrypoint parses request params (CIPPEndpoint, tenantFilter, ForwardingOnly), calls the report function, logs activity and returns HttpResponseContext with appropriate status codes. The report generator reads cached mailbox data via Get-CIPPDbItem, supports a TenantFilter and -ForwardingOnly switch, handles 'AllTenants' by aggregating per-tenant reports, computes forwarding status (External/Internal/Both/None), and returns PSCustomObjects with fields like UPN, DisplayName, PrimarySmtpAddress, ForwardingType, ForwardTo, DeliverToMailboxAndForward, Tenant and CacheTimestamp. Error handling and logging added for missing data and per-tenant failures.

Add UseReportDB query handling to fetch mailbox forwarding from the report DB (Get-CIPPMailboxForwardingReport). If UseReportDB=true the report function is called and returned; otherwise the code performs a live Exchange Online query (Get-Mailbox via New-ExoRequest), selects relevant fields and projects normalized PSCustomObjects with ForwardingType, ForwardTo, HasForwarding, and related properties. Also improve logging and error handling for both paths.

A mailbox forwarding report should only contain mailboxes with forwarding.
