refactor: remove Repository CR pipelinerun_status field

Remove the Status []RepositoryRunStatus field from the Repository
CR to eliminate informer cache churn caused by updating the CR on
every PipelineRun completion. CLI commands now query PipelineRuns
directly via label selectors instead of reading repo status.

- Delete updateRepoRunStatus reconciler method and call site
- Rewrite MixLivePRandRepoStatus to query only PipelineRuns
- Fix pre-existing bug: copy CompletionTime in PR conversion
- Remove pipelinerun_status schema and printcolumns from CRD
- Delete dead code: ShowLastSHA, ShowStatus, ShowLastAge
- Update deepcopy, test helpers, informer transform, golden files
