Merge krystie-improvements into main

Resolves 24 conflicts between Hermes (DC-008/009/010 + response-helper
envelope standardization) and Krystie (DC-005 src/ refactor path fixes,
DC-006 TOTP integration, DC-007 new test suites, cloud backup
destinations).

Conflict resolutions:
- src/utils/logging.js:    took ours (consumers depend on logError/
                            safeErrorMessage/createLogger exports)
- src/config/site.js:      merged (her factored validateAndLogConfig +
                            applyConfigFields helpers)
- src/context/dns.js:      took hers (admin/readonly role iteration for
                            write operations)
- src/utilities/backup-
  manager.js:              took hers (Dropbox/WebDAV/SFTP cloud feature)
- status/dist/*, status/
  sw.js:                   took hers (minified bundles + newer SW cache)

Additional fix (post-merge regression):
- src/monitoring/health-checker.js: fixed DC-005 path miss —
  'require(./platform-paths)' → 'require(../../platform-paths)'

Test status: 921/922 passing. One known failure in logging.test.js
(async file-handle timing) tracked as follow-up.

+ * Integration tests for routes/auth/totp.js — the full TOTP auth flow.
+ *
+ * Covers the BACKLOG.md DC-006 acceptance criteria:
+ *   - no code      → 400 (ValidationError)
+ *   - wrong code   → 401 (AuthenticationError)
+ *   - valid TOTP   → 200 + session cookie + CSRF token
+ *   - check-session with valid session → 200 { authenticated: true }
+ *   - check-session without session    → 401 (AuthenticationError)
+ *
+ * Uses real otplib for code generation (so we exercise the actual TOTP math)
+ * but mocks credentialManager, session, totpConfig, and saveTotpConfig —
+ * because those modules own their own state machines (disk, cookies, file)
+ * that don't belong in a routes-level test.
+ *
+ * NOTE: this test exercises the src/ refactored module layout (DC-005).
+ * It depends on routes/auth/totp.js requiring ../../src/utilities/errors and
+ * ../../src/utils/responses — fix the relative paths in totp.js if they
+ * regress (see commit log for DC-006).
