Consolidate response helpers and error logger to single modules

Two cleanups in one pass for the v1.14.0 'works on any platform' theme:

1. Response helpers — merged src/utils/responses.js and the root-level
   response-helpers.js into a single module at src/utils/responses.js.
   The old module had a richer set (created, noContent, validationError,
   unauthorized, forbidden, notFound, conflict) and is now re-exported
   from the new location. Updated 15 routes to import from
   src/utils/responses and deleted the root response-helpers.js.

2. Error logger — error-handler.js now uses the unified
   src/utils/logging.js#logError (same one src/app.js uses), so all errors
   go to one log file with one rotation policy. Removed the dead
   asyncHandler export (the real one is in src/utils/async-handler.js
   and is used everywhere). Deleted the legacy error-logger.js.

Both are invisible to users — same HTTP response shapes, same log file
path, same error format. Internal-only refactor.

+ * Config migration tests
+ *
+ * These tests verify that a config file from any older version of DashCaddy
+ * gets correctly migrated to the current version. Migration MUST be:
+ *   - Deterministic (same input always produces same output)
+ *   - Idempotent (running migration on already-migrated config is a no-op)
+ *   - Safe (no data loss; only adds fields, never removes user values)
+ *   - Silent (no exceptions thrown for any version from 0 to CURRENT)
