fix(core): count live optional-gate sessions (code review, plan review) as running agents

An In Review column with one MERGING task and one live CODE REVIEW task showed
1/2 processing: gate sessions run with task.status left null, so the shared
isRunningAgentTask predicate only saw the merge-pipeline statuses. Count a
pending workflow-step-result lease (the durable live-gate signal; FN-8492
fails orphaned ones) as Running on any unpaused, non-terminal row. Covers
plan review, code review, browser verification, post-merge verification, and
custom optional steps across column headers, footer stats, admission, and CLI.

+dev: `isRunningAgentTask` treats a `pending` workflow-step-result lease as Running; shared by column headers, footer stats, admission, and CLI counts.
