feat(agent): add QuickForm escalation channel models

Introduce a discriminated-union hierarchy for escalation channels
(BaseEscalationChannelProperties, AgentActionCenterEscalationChannel,
AgentQuickFormEscalationChannel) so QuickForm escalations carry their
FormLib schema instead of an Action Center app reference.
