BlueBubbles webhook POST returns 404 despite plugin reporting 'webhook listening' #49395
Description

Version: OpenClaw 2026.3.13 (61d171a)
OS: macOS Tahoe 26.4.0 (arm64)
BlueBubbles Server: 1.9.9
Problem
POST requests to the BlueBubbles webhook path return 404, while GET returns 200 (SPA catch-all HTML).
Config
channels: {
bluebubbles: {
enabled: true,
serverUrl: "http://192.168.68.64:1234",

Gateway startup log shows:

[bluebubbles] [default] BlueBubbles Private API enabled
[bluebubbles] [default] BlueBubbles webhook listening on /bluebubbles-webhook
But:

Notes
- Outbound messaging (send via REST API) works fine
- This was previously working (outbound messages were sent at 4:43 PM on 3/16)
- Multiple gateway restarts (SIGUSR1 + full manual restart) don't fix it
- No config changes were made between working and broken states
- Plugin plugin entry is enabled in plugins.entries.bluebubbles
