Accept flat-spec input aliases across generators

Harden bizcase, bom, deck, and diagram generators to tolerate payload
shape variants (metadata/cover/summary/line_item aliases, current_state
as string, alternate pillar keys) so MCP and CLI flat specs render
consistently. Add input-alias tests per generator.

Also loosen KB governance tests to handle multi-document service YAMLs
with optional changelogs, untrack the customer demo output under
examples/output-demo-pharma-mx/ (matches .gitignore), and ship an
ADB-S vs Aurora 500GB sample deck.
