fix: resolve dashboard issue creation and GitHub pull failures

- Make description optional in issue creation schema to match frontend
  which sends {title, context, priority} without description field
- Add projectPath parameter to pullIssuesFromGitHub so gh command runs
  in the correct git repo directory instead of process.cwd()
- Fix issueDialogStore to send priority as string enum, add description
  field, and read correct response path (result.data?.issue?.id)
