The first-five-minutes journey test proves a new forge's first ask reaches a running build within 60 seconds #11346

Replaces the acceptance of #11278 (part of #11158).

Done:

• [ ] A test on a spawned forge with a stub model: claim, first ask, then within 60 s a new app exists, a run on its issue is in progress, and the home card names who is on it.
• [ ] The test fails if the ask is filed on the forge repository or only kept as a thought.
• [ ] After release the steward runs the same journey on a throwaway production forge with the real $2 credit and records its cost against that forge's credit (a note on this issue; not a builder's step).

One test file, listed in the gate.
