fix: align BlueBubbles private-api null fallback + warning (#23459) (thanks @echoVic)

CHANGELOG.md

@@ -64,6 +64,7 @@ Docs: https://docs.openclaw.ai
 - Chat/UI: strip inline reply/audio directive tags (`[[reply_to_current]]`, `[[reply_to:<id>]]`, `[[audio_as_voice]]`) from displayed chat history, live chat event output, and session preview snippets so control tags no longer leak into user-visible surfaces.
 - Telegram/Retry: classify undici `TypeError: fetch failed` as recoverable in both polling and send retry paths so transient fetch failures no longer fail fast. (#16699) thanks @Glucksberg.
 - BlueBubbles/DM history: restore DM backfill context with account-scoped rolling history, bounded backfill retries, and safer history payload limits. (#20302) Thanks @Ryan-Haines.
+- BlueBubbles/Private API cache: treat unknown (`null`) private-API cache status as disabled for send/attachment/reply flows to avoid stale-cache 500s, and log a warning when reply/effect features are requested while capability is unknown. (#23459) Thanks @echoVic.
 - BlueBubbles/Webhooks: accept inbound/reaction webhook payloads when BlueBubbles omits `handle` but provides DM `chatGuid`, and harden payload extraction for array/string-wrapped message bodies so valid webhook events no longer get rejected as unparseable. (#23275) Thanks @toph31.
 - Security/Audit: add `openclaw security audit` finding `gateway.nodes.allow_commands_dangerous` for risky `gateway.nodes.allowCommands` overrides, with severity upgraded to critical on remote gateway exposure.
 - Gateway/Control plane: reduce cross-client write limiter contention by adding `connId` fallback keying when device ID and client IP are both unavailable.
