fix: correct OpenCode portal workspace link

[xnoto]

Summary

Correct the OpenCode portal card's base64url directory slug so it targets /home/opencode, rather than the nonexistent /homeopencode path.

Fixes # N/A (no tracking issue)

Type of change

• Bug fix
• Feature / enhancement
• Documentation
• Infrastructure (OpenTofu root or module)
• GitOps desired state (manifests, kustomize, charts, SOPS/KSOPS secrets)
• Container image
• CI / reusable workflow
• Refactor / cleanup
• Breaking change

Validation

• Required pull-request checks pass — pending
• Generated or centrally distributed files were regenerated by their owning automation, not hand-edited — not applicable; this repository owns the static portal source.

Verified the exact one-line diff and matched the corrected slug to OpenCode v1.18.23's base64url encoder and legacy session-route contract. No local validation was run.

Impact and rollout

Canonical source: www/makeitwork.cloud/index.html. The change affects only the public OpenCode portal card. After a confirmed merge, the existing www deployment workflow will run static checks, sync the static site to S3, and purge Cloudflare cache. No chart, GitOps desired state, OpenCode workload, or runtime configuration changes.

Post-merge functional verification: open the portal card and confirm the authenticated web UI selects /home/opencode.

Safety and secrets

• Contains no plaintext secrets, decrypted SOPS values, state files, kubeconfigs, tokens, or private endpoints
• No local OpenTofu init/plan/apply/destroy/import/state operations were run or claimed — plans come from pull-request checks
• Breaking or irreversible effects are described above with rollback notes — revert this one-line source change if needed.
