feat(portfolio): complete RESOURCE-WP-0003 T06 optimization cases and T07 reporting

T06: optimization-case schema, fail-closed evaluator, cadence and decision
template. Every option including the baseline must present all ten decision
fields; one unknown blocks the comparison. Validated on the storage case
(Hetzner computes and loses to Scaleway by EUR 29.14/month on operator labour;
Host Europe blocks on four named gaps) and on the non-storage reef-railiance
k3s rightsizing case (low utilization is real, but nothing is costable while
the railiance01 price is unknown).

T07: portfolio report over coverage, lifecycle, utilization, cost, renewals,
risks, open cases, and next actions, derived only from committed evidence.
Portfolio spend is reported null rather than as a partial sum, unattributed
cost is a named list rather than a spread, and unmeasurable resources are
reported rather than dropped.

RESOURCE-WP-0003 is finished; both cases remain blocked_on_evidence against
live delegated records in other repositories. RESOURCE-WP-0002 is untouched.
