fix: missing model_operations.models table + compliance schema breaking every fresh DB (live deploy failure)

The SCP/DbMigrator deploy to the production target (178.104.200.7)
failed today with `relation "model_operations.models" does not
exist` at migration 0036 — the exact same failure I'd already hit
against a local test database, confirming this isn't environment
drift but a real, deterministic bug: no migration ever created
model_operations.models, only referenced it via FK (0036, 0038) and
queried it directly (OpenDartDailyBatchJob.cs). Migration 0037 had
the same class of bug for the `compliance` schema itself.

- Add 0035_model_operations_models.sql (must sort before 0036).
  Scope is intentionally minimal — id/ticker/published_at/
  correlation_id/revision, i.e. only what's actually referenced
  today. The full Model Card/lifecycle schema is separate, larger
  work and isn't guessed at here.
- Add `CREATE SCHEMA IF NOT EXISTS compliance;` to 0037, plus
  IF NOT EXISTS on its indexes for re-run idempotency (matching the
  rest of this migration set).
- Verified: full chain 0000->0040 applies to a fresh DB
  ("Upgrade successful") and re-run is a clean no-op
  ("No new scripts need to be executed").

Fixing the schema far enough to actually run queries against it
surfaced 3 more real, previously untested bugs in already-merged
code (none reachable before because the tables/schema didn't exist):

- Dapper was never configured for snake_case<->PascalCase column
  mapping (`Dapper.DefaultTypeMap.MatchNamesWithUnderscores`), so
  every Sql class's result-set queries were silently returning
  null/default for every property instead of throwing. Fixed once,
  centrally, via a `[ModuleInitializer]` in
  KArtSell.BuildingBlocks/Data/DapperBootstrap.cs so it's set before
  the first query regardless of entry point (Host/DbMigrator/tests).
- jsonb/inet columns written without an explicit cast
  (`42804: column "x" is of type jsonb but expression is of type
  text`) in AuditSql (details, ip_address), TradeSql (kis_response),
  SellDecisionSql (oos_performance) — fixed with `::jsonb`/`::inet`
  casts. AuditSql's jsonb read-back into Dictionary<string,object>
  also needed a raw-DTO + JsonSerializer.Deserialize mapping.
- AuditSql.RedactAuditEventDetailsAsync had a literal duplicate
  `SET details = ... details = ...` (invalid SQL) — nested the two
  jsonb_set calls into one assignment.

Verified: dotnet build 0/0; architecture 13/13; unit 54/54+18/18;
Host boots cleanly and registers all 34 endpoints against the
now-complete schema.

New tech debt recorded: DEBT-020 (this fix), DEBT-021 (Dapper
snake_case fix), DEBT-022 (jsonb/inet casts, partial — not yet
audited beyond what surfaced), DEBT-023 (ApprovalSql.
InsertProposalAsync still fails on a raw DateOnly parameter — same
class of issue as DEBT-021, not yet fixed), DEBT-024 (TradeExecution
tests don't insert FK parent rows; one pure-logic ranker test
returned 1000 instead of 950 under the full suite, not yet
root-caused; DbUpMigrationTests fail locally on a Postgres role
permission gap unrelated to this fix).
