Add a manual release/requeue escape hatch to the portfolio-queue CLI

[JSONbored]

Problem: The portfolio-queue CLI only exposes list/next/done — there's no way for an operator to manually release or requeue an item without the automated reclaim above.

Area: AMS / CLI

Proposal: Add release and requeue subcommands to the portfolio-queue CLI.

Deliverables:

• Two new subcommands with clear, documented behavior and exit codes.

Acceptance criteria:

• release <id> and requeue <id> both work against a live queue and are reflected in list immediately.

Boundaries:

• CLI surface only — no change to the underlying queue schema beyond what the lease work above requires.
