fix: harden synology chat TLS helper defaults

CHANGELOG.md

@@ -93,6 +93,7 @@ Docs: https://docs.openclaw.ai
 - Device pairing: reject rotating device tokens into roles that were never approved during pairing, and keep reconnect role checks bounded to the paired device's approved role set. (#60462) Thanks @eleqtrizit.
 - Mobile pairing/security: fail closed for internal `/pair` setup-code issuance, cleanup, and approval paths when gateway pairing scopes are missing, and keep approval-time requested-scope enforcement on the internal command path. (#55996) Thanks @coygeek.
 - Exec approvals/node host: forward prepared `system.run` approval plans on the async node invoke path so mutable script operands keep their approval-time binding and drift revalidation instead of dropping back to unbound execution.
+- Synology Chat/security: default low-level HTTPS helper TLS verification to on so helper/API defaults match the shipped safe account default, and only explicit `allowInsecureSsl: true` opts out.
