docs: KMP platform logo + wizard taxonomy (no wip — merge last) (#18516)

* docs: add KMP platform logo and restore wizard taxonomy entry

Follow-up to #18472 (merged):
- Add the Kotlin logo to logos.ts under key `kmp` (uploaded to Cloudinary
  alongside the other integrate logos) and reference it from the KMP page via
  `platformLogo: kmp`
- Re-add the Kotlin Multiplatform entry to installation-taxonomy.ts, which was
  dropped from the #18472 squash-merge. Both the docs page header and the
  wizard framework row resolve the same getLogo('kmp'), so this single logo
  lights up both surfaces.

* docs: drop wip from KMP wizard entry (merge last, after wizard is live)

Consolidates the planned drop-wip change into this PR. Removing status: 'wip'
means KMP shows as a full wizard target (no "Coming soon"), which is only
accurate once wizard auto-install is live. This PR must therefore merge LAST —
after context-mill#240 (with mcp-publish → release) and wizard#906 land.
