Teknium 57481c8ac5 fix(tools): implement send_message routing for Matrix, Mattermost, HomeAssistant, DingTalk (#3796)
* fix(tools): implement send_message routing for Matrix, Mattermost, HomeAssistant, DingTalk

Matrix, Mattermost, HomeAssistant, and DingTalk were present in
platform_map but fell through to the "not yet implemented" else branch,
causing send_message tool calls to silently fail on these platforms.

Add four async sender functions:
- _send_mattermost: POST /api/v4/posts via Mattermost REST API
- _send_matrix: PUT /_matrix/client/v3/rooms/.../send via Matrix CS API
- _send_homeassistant: POST /api/services/notify/notify via HA REST API
- _send_dingtalk: POST to session webhook URL

Add routing in _send_to_platform() and 17 unit tests covering success,
HTTP errors, missing config, env var fallback, and Matrix txn_id uniqueness.

* fix: pass platform tokens explicitly to Mattermost/Matrix/HA senders

The original PR passed pconfig.extra to sender functions, but tokens
live at pconfig.token (not in extra). This caused the senders to always
fall through to env var lookup instead of using the gateway-resolved
token.

Changes:
- Mattermost/Matrix/HA: accept token as first arg, matching the
  Telegram/Discord/Slack sender pattern
- DingTalk: add DINGTALK_WEBHOOK_URL env var fallback + docstring
  explaining the session-webhook vs robot-webhook difference
- Tests updated for new signatures + new DingTalk env var test
