FN-5848: clarify onboarding and git test expectations

Clarifies test expectations around onboarding auto-launch and non-matching integration tips.

- Rename the onboarding marker test to describe central DB gating accurately.
- Assert task-list routing when onboarding is skipped after central DB creation.
- Avoid accidental matching SHA construction in the git advance pending test.
