Maurice a634b2a26b feat(server): give the scheduler a contract with the container (#1827)
The scheduler runs outside the Nest container but needs four things inside it:
backupService, trekPhotoCache, placePhotoCache and airtrailSync. It reaches all
four with a require() or await import() at call time. This settles how that
should work before four separate folds each invent their own answer, and wires
one consumer as proof.

It takes the dependencies from the container rather than growing four more
bridges, for a reason that showed up while writing the previous PRs: adding one
constructor parameter to a service meant hand-editing five bridge files that
rebuild their services with `new`. app.get() has no such cost, and hands back
the container singleton instead of a second instance.

The scheduler declares what it needs structurally — a `backups` with a
createBackup — and never names BackupService. That is not fastidiousness: an
import of the class would pull in src/nest/backup → src/services/backupService →
src/scheduler, which is the exact cycle the lazy `await import()` in runBackup
existed to dodge. With the dependency handed in, the scheduler stops importing
backupService entirely and the cycle is gone; backupService still imports the
scheduler for VALID_INTERVALS, but now only in one direction.

index.ts fills the contract from the app buildApp() already initialised, right
before the first cron starts, the way bootstrap.ts hands the /mcp handler its
registry.

Two smaller things fall out. The Nest BackupService was swallowing
createBackup's prefix parameter, so it could only ever produce 'backup' names;
it forwards it now. And the scheduler can be started without a container at all
— its unit tests do exactly that — so runBackup says so in the log instead of
throwing, with a case covering it.

The other three consumers stay on their require() calls; they move with their
own folds.
