fix(registries+router): MEDIUM/LOW audit batch

closes MEDIUM/LOW from feat/agent-dna-three-layer audit:

- models.toml: cache_write_1h_per_mtok_micro added to all 11 entries
  (Anthropic: 200M/600M/1000M micro = $2/$6/$10 per MTok per pricing page;
   other providers: 0 placeholder)
- main.rs (kei-model-router): WAL pragma + busy_timeout errors now logged
  to stderr instead of silently dropped (previously .ok() swallowed both)
- models.toml: Haiku id pin TODO documented (router still hardcodes alias)
