fix(issue-list): auto-recover when user passes issue short ID instead of project slug (#750)

## Summary
- When a user runs `sentry issue list ARMAX-3E`, the CLI now
auto-recovers instead of throwing a `ResolutionError`
- Detects the issue short ID early in `func()`, resolves it via
`resolveIssue()`, and shows it as a single-item list result with a
warning and a hint toward `sentry issue view`
- Follows the established auto-recovery pattern from `event/view` and
`trace/view` commands

Fixes CLI-159
