feat(admin): add KiloClaw subscription controls

[jeanduplessis]

Summary

Add KiloClaw subscription management to the admin user detail page so admins can inspect a user's KiloClaw subscription state and edit the KiloClaw trial expiration date without leaving /admin/users/[id].

This adds admin tRPC read/write endpoints for KiloClaw subscription state, records trial-date edits in the KiloClaw admin audit log, and adds a dedicated KiloClaw card in the existing admin user dashboard. The trial date editor now preserves the admin's local calendar date when reopening and saving a value.

Verification

• pnpm exec tsc -p tsconfig.json --noEmit --pretty false --incremental false
• git push -u origin kiloclaw-billing-admin (pre-push hooks ran pnpm run format:check, pnpm run lint, and pnpm run typecheck successfully)
• pnpm test -- src/routers/admin-kiloclaw-user-router.test.ts could not complete in this environment because the test Postgres setup was unavailable

Reviewer Notes

Admin trial-date editing is intentionally limited to existing trialing KiloClaw subscription rows. The organization trial editor appears to use the older UTC/local date pattern too, but this PR only fixes the KiloClaw admin flow.
