Extract SecureHttpClientService into its own module (#17828)

## Summary

- **Extract `SecureHttpClientService`** from `tool` module into a
dedicated `core-modules/secure-http-client/` module with proper NestJS
module encapsulation
- **Fix module hygiene**: 12 modules that incorrectly listed
`SecureHttpClientService` as a direct provider now properly import
`SecureHttpClientModule`
- **Add structured logging** for outbound HTTP requests with
workspace/user context (for GuardDuty alert correlation)
- **Rename type files** to follow one-export-per-file convention
(`get-secure-axios-adapter.types.ts` ->
`secure-adapter-dependencies.type.ts`, new
`outbound-request-context.type.ts` / `outbound-request-source.type.ts`)

### Why

`SecureHttpClientService` is a cross-cutting concern (used by auth,
captcha, file upload, geo-map, telemetry, admin-panel, REST API, contact
creation, webhooks, and workflow tools) but was bundled inside the
`tool` module. Most consumers worked around this by listing it as a
direct provider instead of importing a module, which is fragile and not
idiomatic NestJS.

## Test plan

- [x] All 60 unit tests pass (`secure-http-client.service.spec.ts`,
`get-secure-axios-adapter.util.spec.ts`, `is-private-ip.util.spec.ts`)
- [x] Related module tests pass (admin-panel, contact-creation, tool)
- [x] `npx nx typecheck twenty-server` passes
- [x] `npx nx lint:diff-with-main twenty-server` passes
- [x] Server compiles and bootstraps successfully
