chore(hub): clean up legacy Captain hub flow (#13640)
## Summary
This PR cleans up legacy Hub/Captain integration paths and simplifies
hub URL behavior coverage in tests.
## Changes
- remove legacy Captain account endpoint flow from `ChatwootHub`
- remove obsolete spec coverage tied to that retired flow
- keep hub URL handling centralized in `base_url` with enterprise
overlay precedence
- simplify hub URL specs to assert explicit static URL expectations
where applicable
## Reproduce
Run the focused hub specs from this branch:
- `bundle exec rspec spec/lib/chatwoot_hub_spec.rb
spec/enterprise/lib/chatwoot_hub_spec.rb`
## Testing

- `bundle exec rubocop lib/chatwoot_hub.rb spec/lib/chatwoot_hub_spec.rb
