refactor(services): leave CLI flag and command names to the app layer

Services report ErrRunScanExhausted, ErrMaxPages and plain conflicts,
and the commands add the --branch/--max-pages/--force hints. Unknown
label names use the shared NotFoundError, and the repository-scoped
review and team search refusal moves into tea search's own usage
check.
