feat!: scope per-app config and settings by environment

BREAKING: wipe dev PostgreSQL before deploying — V1 checksum changes.
Agents must now send environmentId on registration (400 if missing).

Two tables previously keyed on app name alone caused cross-environment
data bleed: writing config for (app=X, env=dev) would overwrite the row
used by (app=X, env=prod) agents, and agent startup fetches ignored env
entirely.

- V1 schema: application_config and app_settings are now PK (app, env).
- Repositories: env-keyed finders/saves; env is the authoritative column,
  stamped on the stored JSON so the row agrees with itself.
- ApplicationConfigController.getConfig is dual-mode — AGENT role uses
  JWT env claim (agents cannot spoof env); non-agent callers provide env
  via ?environment= query param.
- AppSettingsController endpoints now require ?environment=.
- SensitiveKeysAdminController fan-out iterates (app, env) slices so each
  env gets its own merged keys.
- DiagramController ingestion stamps env on TaggedDiagram; ClickHouse
  route_diagrams INSERT + findProcessorRouteMapping are env-scoped.
- AgentRegistrationController: environmentId is required on register;
  removed all "default" fallbacks from register/refresh/heartbeat auto-heal.
- UI hooks (useApplicationConfig, useProcessorRouteMapping, useAppSettings,
  useAllAppSettings, useUpdateAppSettings) take env, wired to
  useEnvironmentStore at all call sites.
- New ConfigEnvIsolationIT covers env-isolation for both repositories.
