fix(ses): preserve h1 elements — do not strip first heading

Songs always carries a # Song title line so stripping makes sense there,
but SES body structure is freeform and may use h1 deliberately.

+Plain markdown. The body is passed through Pandoc as-is — the first-line `# Heading` is not stripped, so you can use h1 elements freely. Do not embed raw wikitext (`{{Template}}`, raw `[[Wikilinks]]`, etc.) unless you intend the literal output.

 6. Read the current wiki page content via the MediaWiki API; if identical to the generated output, skip the write (idempotency).
