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

Browse source 
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.

"notes": [
"Observed workload is less than one day old; scenario floors intentionally dominate the raw sample.",
"Storage forecast assumes 30 retained daily base backups plus 30 days of WAL and is conservative because it does not model compression or Barman's exact point-of-recoverability deletion timing.",
"Provider exit is modeled as one full stored-byte egress event and is reported separately from recurring monthly cost."
