Captain can now use each assistant's saved setting when a customer stops
replying. Captain can review the conversation and resolve or hand it
off, resolve it after the selected time without review, or leave it
pending until the customer replies.
The job checks the conversation again while holding a database lock
before it changes the status. A new customer reply or another worker
cannot cause an outdated resolve or handoff.

## What changed
- Added assistant modes for review, always resolve, and wait for the
customer.
- Kept the account setting as the fallback for assistants that do not
have a saved mode.
- Skipped scheduling when resolution is disabled on the assistant or
through the older account setting.
- Rechecked the conversation status and activity time before each
resolve or handoff.
- Recorded events only after a status change succeeds.
- Kept out of office messages out of campaign conversations.
## How to test
1. Set an assistant to review conversations. Run the inactivity job with
complete and incomplete decisions. Confirm the first conversation is
resolved and the second is handed off.
2. Set the assistant to always resolve. Confirm an eligible pending
conversation is resolved after the selected time.
3. Set the assistant to wait for the customer. Confirm the scheduler
does not enqueue the inactivity job and the conversation remains
pending.
4. Add a customer reply while the review is running. Confirm the job
does not resolve or hand off the updated conversation.
5. Run two workers for the same conversation. Confirm only one status
change and one event are recorded.
