Update transferred callers (umh-custom-code, profile-behavior-custom-code) to pass `transferred: true`

[taprile314]

Part of #20

Scope

Update the two transferred repos so their callers pass transferred: true on every deploy invocation (across preview/stage/production environments).

Acceptance Criteria

• umh-custom-code caller passes transferred: true and stops producing failed deploy runs.
• profile-behavior-custom-code caller passes transferred: true and stops producing failed deploy runs.
• CI jobs (if any) keep running normally in both repos.

Edge Cases

• The flag affects only the deploy step — ci jobs keep running so lint/typecheck/test/build remain useful if someone is still maintaining the repo.

Depends on the sibling issue that adds the transferred input to deploy.yml.
