generate_deck on the MCP server passes a flat spec (customer_name, title,
workload_type, services, cost_summary, ...) — but from_spec only understood
the proposal-spec YAML shape (metadata/summary/architecture/...). With no
matching keys, only the title and closing layouts rendered, both populated
with empty strings, producing a deck that looked blank.
Detect the flat shape in from_spec and adapt it into the proposal-spec
fields that the existing slide builders already consume. Title, summary
(target state + current-state bullets) and cost slides now render from
whatever the MCP tool sends; the richer proposal-spec path is untouched.
