fix: detect issue short IDs passed to issue list (CLI-C3) (#488)

## Problem

When users run `sentry issue list CONVERSATION-SVC-F` or similar
commands with an issue short ID, the CLI interprets it as a project slug
to search for. Since project slugs are always lowercase and short IDs
are uppercase, no project is found and the user sees:

```
ResolutionError: Project 'CONVERSATION-SVC-F' not found.
```

This affects **24 users**
([CLI-C3](https://sentry.sentry.io/issues/7319435132/)).

## Fix

Added a pre-flight check in the `project-search` handler of `issue list`
that uses the existing `looksLikeIssueShortId()` utility to detect when
the input looks like an issue short ID (all-uppercase, dash-separated
with alphanumeric suffix). When detected, throws a helpful
`ResolutionError` that suggests using `sentry issue view` instead:

```
'CONVERSATION-SVC-F' looks like an issue short ID, not a project slug.

Try:
  sentry issue view CONVERSATION-SVC-F

Or:
  - To view this issue: sentry issue view CONVERSATION-SVC-F
  - To list issues in a project: sentry issue list <org>/<project>
```

## Key Design Decisions

- Uses the existing `looksLikeIssueShortId()` pattern which requires
all-uppercase with dash separators — this avoids false positives on
legitimate lowercase project slugs
- Check runs before the API call to `findProjectsBySlug`, saving a round
trip
- Uses `ResolutionError` (not `ContextError`) because the user provided
a value that couldn't be matched
