Subject: [PATCH] feat: advertise TSP alongside DIDComm across all four
 components
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Images are built with TSP; the recipes now match.

- vta-setup.toml (both modes): [services] tsp = true
- mediator-recipe.toml: protocols = ["didcomm", "tsp"]
- webvh-recipe.toml: [identity] transport = "both"
- vtc-setup.toml: [messaging] transports = ["tsp", "didcomm"]

The VTC's `transports` is required — `MessagingSetup` has no serde default, so
a [messaging] table without it fails to deserialize on any vtc image from #929
onward, TSP or not.

full_stack's [messaging] deliberately gains no `protocols` key: omitted, setup
derives the minted mediator's transports from [services].
