feat(portfolio): fold in RAILIANCE-WP-0016 apps-pg evidence

First delegated evidence from RESOURCE-WP-0003-T04 to land. railiance-platform
delivered apps-pg capacity, utilization, consumers, and the apps-pg-dbbytes-v1
allocation driver, and correctly delivered no EUR.

- data/resources/apps-pg.json: real capacity; allocation unattributed -> shared
  under apps-pg-dbbytes-v1; second consumer vergabe-teilnahme registered
- data/control-cycle/apps-pg-2026-09-base.json: first operational control-cycle
  record in the repository
- examples/control-cycle/apps-pg-*.json retired; the invented fixture collided
  with the real record's identifier
- data/portfolio-coverage-2026-08-14.json: gap marked delivered with three
  residual unknowns still open

The real evidence exposed a design gap in the T05 schema: v0.1 required a number
for every cost field, so recording genuine usage without a booked cost meant
inventing one. Schema 0.2 permits null costs, null unattributed_eur, a technical
unattributed_share, and null measurements. Null is unknown, never zero; an
unknown component makes the total null rather than the sum of the known parts;
and the comparator classifies unknown amounts as data_quality instead of
computing a variance. Existing 0.1 records are not rewritten.

apps-pg is now measured (idle at 5.8% of volume) and attributed, and remains
unpriced: delivered technical evidence does not create a booked cost.

86 tests pass.
