Fix slide and diagram bugs in deck/diagram generators

Browse Source 
Service Tiering slide no longer falls back to the workload `name`
field for the tier label, which previously rendered "Bronze Bronze"
when the spec only carried tier names. Uptime/RTO/RPO now fill from
tier defaults when the spec omits them.

Architecture Principles slide enriches caller-supplied items with
name + summary from the KB when only the principle id is given,
instead of rendering bare placeholders like "P-01 P-02".

Architecture Overview slide auto-builds a two-region visual when the
proposal spec names a `dr_region` but doesn't pre-render `architecture.visual`,
so DR is no longer dropped from the deck.

Diagram generator gained a region-level `local_dr` flag that adds a
"Local DR Standby" dormant node inside the region, and now auto-wires
an "RPC (Remote Peering)" edge between DRGs when the spec defines
two or more regions with DRGs but no manual peering connection.
