feat(addon): add ActiveBlue AI bot to Odoo Discuss

- Create res.partner for the AI bot (appears in DM contacts)
- Override mail.channel.message_post to intercept direct messages
  to the bot partner and forward them to the agent service
- Post the agent reply back into the Discuss channel as the bot
- Add discuss to depends; load res_partner_bot.xml data

Users can now open Discuss -> New Message -> search 'ActiveBlue AI'
to start a conversation with the agent.
