Add language identifiers to the new fenced code blocks.

markdownlint reports MD040 for these fences. Add shell after each opening fence to remove the warnings and enable consistent command highlighting.

- Line 130: Clarify the legacy metadata fallback statement to apply only to
single-team scoped exports. Update the description around ExportScopeAdditional
and --destination-team-name so multi-team exports still require the documented
failure behavior, while legacy single-team exports infer the source team from
the first team entry.
- Line 204: Update the “Monitor the job” step to qualify checkpoint detection
and resume prompts: state that they apply only to imports with at least 100 MB
of uncompressed JSONL, the same filename, and an interactive terminal.
- Around line 230-231: Update the mmctl export download example to use the
export name returned by mmctl export list as its first argument, while retaining
or clearly separating the desired local destination filename as the second
argument.

…r scoped migration

Align the team/channel migration docs with the shipped mmctl flags:

- Add the --imported-users flag (required for any scoped export) to the
  import flags table, and thread active|inactive through every import
  example and the migration steps.
- Add the --include-custom-emoji export flag.
- Reword the placeholder-account behavior notes to reflect that
  deactivation and importedInactive tagging are governed by
  --imported-users inactive rather than being unconditional.

🟡 Minor · Document the single-channel and single-team requirements. · site/content/contribute/more-info/server/cli-commands.md:137-140

137-140: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Document the single-channel and single-team requirements. --destination-channel-name also requires exactly one source channel and exactly one source team. The import validation in server/channels/app/import.go rejects multi-channel or multi-team scoped exports, so the documentation should state these constraints.
