Add omni-moderation-latest to affected channel model lists.

When model is omitted, moderation requests use omni-moderation-latest. Existing channels configured only with text-moderation-stable can then be excluded from channel selection. Add the new model to those channel lists before rollout.

Document this channel-list migration separately. The existing token-limit note concerns token model allowlists, not channel model lists.

Review comment at @middleware/distributor.go at line 391:
Update the channel model lists that currently include text-moderation-stable to
also include omni-moderation-latest, matching the default assigned to
modelRequest.Model when the model is omitted. Document this channel-list
migration separately from the token-limit note.
