Maurice d95aa49c7f Split the trip aggregate root into its parts
TripsService injected fourteen other services. Almost all of them were there
for two read aggregates - the MCP trip summary and the offline bundle - and
for the member roster, not for anything the write path does. Reading is what
fans out; writing is not.

Membership goes to trip-members/: listMembers, addMember, removeMember,
transferOwnership and the four guest methods, plus the six routes, which keep
their paths. It is a NEW module, not the trip-membership/ leaf next door:
deleting a guest erases their plugin data and re-splits their expenses, so it
needs auth and budget, and AuthModule already imports that leaf. Giving it
those dependencies there would have closed a hard cycle. This one is a sink -
nothing imports it back except trips.

The read aggregates go to trip-read-model/, which is where the nine-service
fan-out now lives.

What is left is the write core plus day generation, on eight parameters
instead of fourteen: database, reservations, days, permissions, budget,
vacay, realtime, unsplash. The last four are all reachable from updateTrip's
date-shift transaction, which is why the count does not fall to three.

Trips still reaches budget through ReservationsModule, so trips.bridge.ts
survives this. Saying otherwise would have been the easy claim to make and it
would not have been true.
