Add APIv3 Wiki Pages CRUD, forms, schema, and activities

[asymetryk]

Summary

• Expands the stub GET /api/v3/wiki_pages/{id} into a Versions-shaped Wiki Pages APIv3: collection index, project-scoped listing, create/update with forms + schema, delete with hierarchy todo semantics (nullify / destroy / reassign), and journal activities.
• Reuses existing WikiPages::{Create,Update}Service and contracts; adds WikiPages::DeleteService / DeleteContract (delete requires :manage_wiki, matching UI destroy).
• Updates OpenAPI paths/schemas and FAQ so wiki pages can be created/updated/deleted via API.

Motivation

Community and FAQ previously stated wiki content could not be updated via API. Domain services already exist; this exposes them with HAL+JSON, IDOR-safe visibility (WikiPage.visible), optimistic locking via lockVersion, and documented distinction from journal version.

Test plan

• bundle exec rspec spec/requests/api/v3/wiki_pages/ wiki_pages_resource_spec.rb spec/lib/api/v3/wiki_pages/ spec/services/wiki_pages/delete_service_spec.rb
• Manual: create page with Markdown text + project link; PATCH with stale lockVersion → conflict; DELETE leaf; DELETE parent with children requires todo
• Verify attachments sub-resource still works; activities require :view_wiki_edits
• Confirm OpenAPI /api/v3/spec.yml lists new wiki_pages paths

Homelab / deploy note

Self-hosted instances on 17.5.x should upgrade to a release containing this change rather than carrying a long-lived fork patch.
