Form submission writes and submits data through a public share link, an
irreversible action that should require explicit confirmation. Reclassify
the shortcut from write to high-risk-write so the runner's --yes gate fires
before execution, matching +form-delete and other high-risk base commands.
Update the lark-base skill docs (--yes on all examples, param table, tips)
and add tests pinning the confirmation gate (unit) and dry-run structure (e2e).
