DEV: Remove old TODOs for message-id formats (#27196)

Browse Source 
Introduced back in 2022 in
e3d495850d,
our new more specific message-id format for inbound and
outbound emails has now been in use for a very long time,
we can remove the support for the old formats:

`topic/:topic_id/:post_id.:random@:host`
`topic/:topic_id@:host`
`topic/:topic_id.:random@:host`
