Tracks company recency from linked contact activity so the Companies
list and detail page can show/sort by real customer engagement instead
of generic record updates.
## Closes
None.
## Why
Company recency should reflect activity from people associated with the
company. This keeps the signal tied to persisted contact activity,
without treating passive online presence or widget heartbeat pings as
company activity.
## What Changed
- Adds a company helper to record `last_activity_at` from linked contact
activity.
- Rolls up `Contact#last_activity_at` changes to the associated company.
- Initializes company activity when an already-active contact is
associated with a company, including the business-email auto-association
path.
- Throttles company activity rollups to once every 5 minutes per company
to avoid unnecessary writes during active conversations.
- Treats company activity as monotonic: unlinking, moving, or deleting
contacts does not move a company's activity timestamp backwards.
- Leaves historical backfill, online presence tracking, widget visit
tracking, and richer activity attribution out of scope.
## How to Test
1. Open an account with Companies enabled and visit the Companies list.
2. Trigger activity for a contact that belongs to a company, for example
by receiving or sending a message in that contact's conversation.
3. Confirm the linked company shows a recent activity timestamp in the
Companies list/detail page after the contact activity updates.
4. Associate an already-active contact with a company and confirm the
company receives that contact's existing activity timestamp.
5. Confirm repeated contact activity within a short window does not
continuously rewrite the company timestamp.

## Description
Implements company backfill migration infrastructure for existing
contacts. This is **Part 1 of 2** for the company model production
rollout as described in
[CW-5726](https://linear.app/chatwoot/issue/CW-5726/company-model-setting-it-up-on-production).
Creates jobs and services to associate existing contacts with companies
based on their email domains, filtering out free email providers (gmail,
yahoo, etc.) and disposable addresses.
**What's included:**
- Business email detector service with ValidEmail2 (uses
`disposable_domain?` to avoid DNS lookups)
- Per-account batch job to process contacts for one account
- Orchestrator job to iterate all accounts
- Rake task: `bundle exec rake companies:backfill`
~~*NOTE*: I'm using a hard-coded approach to determine if something is a
"business" email by filtering out emails that are usually personal. I've
also added domains that are common to some of our customers' regions.
This should be simpler. I looked into `Valid_Email2` and I couldn't find
anything to dictate whether an email is a personal email or a business
one. I don't think the approach used in the frontend is valid here.~~
UPDATE: Using `email_provider_info` gem instead.
**Pending - Part 2 (separate PR):** Real-time company creation for new
contacts
## Type of change
- [x] New feature (non-breaking change which adds functionality)
## How Has This Been Tested?
```bash
# Run all new tests
bundle exec rspec spec/enterprise/services/companies/business_email_detector_service_spec.rb \\
spec/enterprise/jobs/migration/company_account_batch_job_spec.rb \\
spec/enterprise/jobs/migration/company_backfill_job_spec.rb
# Run RuboCop
bundle exec rubocop enterprise/app/services/companies/business_email_detector_service.rb \\
enterprise/app/jobs/migration/company_account_batch_job.rb \\
enterprise/app/jobs/migration/company_backfill_job.rb \\
lib/tasks/companies.rake
```
**Performance optimization:**
- Uses `disposable_domain?` instead of `disposable?` to avoid DNS MX
lookups (discovered via tcpdump analysis - `disposable?` was making
network calls for every email, causing 100x slowdown)
