The post_init/post_migrate hook now:
- Uses no_reset_password context to skip Odoo's invitation email flow
- Writes a res_users_log row so the user shows as Confirmed instead of
Pending Invitations (Odoo 18 derives state from log presence)
- Idempotently ensures the partner_activeblue_ai external ID points at
the bot's partner so env.ref() resolves in ab_ai_mail.py
Discovered while fixing the bot DM flow on miaai: even after the user
was created, Discuss showed it as Pending until a res_users_log row was
inserted manually.
