fix(trace): allow 'trace view' to work with org-scoped targets

[sentry]

Previously, running sentry trace view <org>/<trace-id> would fail with a ContextError: Specific project is required. This was due to the trace view command using resolveTraceOrgProject, which explicitly throws an error when an org-scoped target (without a project slug) is provided.

However, the underlying API call (getDetailedTrace) does not actually require a project slug to fetch trace details, making this restriction unnecessary for the trace view command.

This fix addresses the issue by:

1. Introducing a new helper function, resolveTraceOrgOptionalProject, in src/lib/trace-target.ts. This function handles org-scoped targets by returning the organization and trace ID (with an undefined project), allowing the command to proceed. Other target types are delegated to the existing resolveTraceOrgProject to maintain strict project requirements for commands like span list and span view.
2. Updating src/commands/trace/view.ts to use resolveTraceOrgOptionalProject. The command's subsequent logic already correctly handles an optional project, so no further changes were needed there.
3. Updating the relevant unit test in test/commands/trace/view.func.test.ts to reflect the new, correct behavior for org-scoped targets.
4. Addressing minor formatting and linting issues identified by CI.
