FN-5819: allow shared-group members to merge into group branch with auto-merge off

Allow shared branch-group members to continue member→group integration even when project auto-merge is disabled.

- add core helper to detect shared branch-group member integrations and export it
- update engine in-review enqueue/handoff/startup flows to permit shared-member integration while still honoring global/engine pause gates
- keep self-healing from pulling shared-member in-review tasks backward during auto-merge-off maintenance
- expand project-engine and reliability-interaction tests for shared-member autoMerge-off behavior and add FN-5819 backstop docs updates

When `settings.autoMerge: false`, `in-review` is terminal-until-merged by a human. Lifecycle-mutating self-healing must not move these tasks backward, pause/fail them, or re-enqueue them for execution.
Scoped exception (FN-5819): shared-branch-group members (`branchContext.assignmentMode === "shared"`) still run the member→shared-branch local integration step while auto-merge is off. This exception is only for assembling `branch_groups.branchName`; shared-branch → default-branch promotion remains gated by group/global auto-merge.
### Mock provider (test mode)
`testMode?: boolean` is now available in both project and global settings. If project `testMode === true` (or the resolved default provider is `"mock"` at any tier), every AI lane is forced to `mock/scripted`, overriding per-task and per-lane model selections. The dashboard exposes this via the Settings Modal "Enable test mode" toggle and a persistent "Test mode — no real AI calls" banner.
