[Communication] PR8: Added End-to-End Mailbox Test and Communication Config Settings Example

[Joseph0120]

Two files modified:
Assets/Tests/EditMode/MailboxTests.cs -> Added end to end test case to verify high level flow
Assets/StreamingAssets/Configs/Simulations/5_swarms_7_ucav.pbtxt -> Added example usage of setting the latency values in 5_swarms_7_ucav.pbtxt example

📝 Walkthrough

Walkthrough

This change reorganizes the messaging interface hierarchy and introduces network communication configuration support. It removes the standalone IMessagePayload interface file, relocates the interface definition to MessagePayload.cs, and adds a MessageType enum to Message.cs. Comments in PendingMessage.cs are expanded for clarity. A new communication_config block is added to the simulation configuration file, defining default and per-link network latency, jitter, and packet delivery parameters. A corresponding unit test validates that the mailbox applies default and override timings correctly across different agent communication paths.

Code Review

This pull request introduces communication configurations for simulations, defining default link latencies and specific overrides for agent-to-agent communication. It also includes a new unit test to verify that the mailbox correctly handles these timing configurations. Review feedback highlights a potential logical inconsistency in the configuration where vessel-to-missile latency is lower than vessel-to-carrier latency, and suggests refactoring the test to avoid fragile reflection-based calls to private methods.

the MessageType enum (it contains a typo "envolope" and is now misleading),
leaving the new improved class comment that describes Message intact;
specifically remove the orphaned comment block that used to describe the Message
class so only the updated description above the Message class remains and ensure
no other comments are altered.
