Fix agent unavailable error on on-premises in Inbound E-Documents page

[Copilot]

Agent-related code in PopulateTaskInfo() fails on on-premises environments where agents are not available, causing page crash with "Agents are temporarily unavailable" error.

Changes

• Add IsSaaSInfrastructure() check before accessing Agent Task records
• Add ReadPermission() check to ensure user has access to Agent Task table
• Clear AgentTask and AgentTaskStatus at procedure start for consistent UI state

local procedure PopulateTaskInfo()
var
    EnvironmentInformation: Codeunit "Environment Information";
begin
    Clear(AgentTask);
    AgentTaskStatus := '';
    if not EnvironmentInformation.IsSaaSInfrastructure() then
        exit;
    if not AgentTask.ReadPermission() then
        exit;
    // ... agent task lookup
end;

Follows existing pattern in EDocPOCopilotMatching.Codeunit.al for SaaS-only feature guards.

@copilot I would also add something like "If not AgentTask.ReadPermission then exit".

Also ask yourself, do we need to clear the task if we dont find anything, if we already clearaed it before?

Added ReadPermission() check and removed the redundant Clear(AgentTask) after FindFirst() in commit a8e656b.
