fix: correct the P-row misuse and the basis tier ordering

Browse source 
Both from info-tech-canon's review of the restatement.

STRAIN 1 — credential custody was recorded as one unit of class P consumption.
P is purchased platform capacity, and using security.secrets buys none. Removed
the row; the relationship now sits in provisions[].uses_provisions alongside the
object-store dependency, marked explicitly as a proposed extension because
ITC-CAP declares no provision-to-provision relation. Filed as
info-tech-canon/demand/ProvisionRelationships.md (their commit ce17dc4).

BASIS TIERS — their point about invoiced being a fin-hub fact we name rather
than originate exposed a real bug: a strict list order made weakest(["invoiced",
"measured"]) return "measured", implying an invoice outranks a measurement. It
does not outside its own domain. Strength is now a tier — invoiced and measured
are peers, quoted below both — with ties broken deterministically by catalog
order without implying a difference that does not exist.

Also filed info-tech-canon/demand/EvidenceBasis.md at their request, proposing
ITC-GOV as owner rather than ITC-CAP.

187 tests pass.
