Spec: https://claude.ai/artifact/QhKsCqtGNzaVice35nvip9#bcc30d01-27db.m1yth80jczv.20396

Intent: why does this change exist?

• An account needs to change the brokers, topic or auth of a destination without a delete.

System impact: what's affected, including downstream?

• Update uses the body checker of Create, so both apply the same rules.

Preserved behavior: what explicitly stays the same?

• Name, AccountId, Arn and CreatedAt keep their stored values.
• A record of a newer version stays untouched, because this server would drop its new fields.

Intended change: what's different after this PR?

• Update replaces the whole record from the body and sets a new UpdatedAt.

Verification: how do we know this worked, or how would we know if it didn't?

• Unit tests run the handler on mem.
• Functional route tests in s3c-ft-tests and file-ft-tests check the change through Get.
